If you've just been through a miscarriage and you're already wondering about trying again, you're not alone. You may have heard that your body becomes "more fertile" straight after a loss. It's a comforting idea. But is it actually true?

Here's what the evidence says, what happens to your fertility after a miscarriage, and how to think about trying again when you feel ready.

The short answer: there's no good evidence that a miscarriage gives you a biological fertility boost. What is true is that your body can ovulate again surprisingly quickly, sometimes before your next period arrives. That's different from being "more" fertile. It means fertility can return sooner than you might expect after a loss. 

Research into fertility after miscarriage isn't completely uniform. Some studies have found slightly lower fecundability (the chance of conceiving in a given menstrual cycle) after a previous miscarriage, while others suggest that most people with a previous miscarriage have a similar chance of becoming pregnant over 12 months of trying.⁷ So there's no good basis for promising a post-miscarriage fertility boost, but neither does a single miscarriage usually mean you'll have trouble conceiving again.

One thing the evidence does suggest is that there is generally no medical benefit to deliberately delaying conception for several months after an uncomplicated early miscarriage. Studies have found that conceiving within a few months is not associated with worse outcomes, and some research has found a lower risk of repeat miscarriage compared with longer intervals.⁸ ⁹

That doesn't mean you should feel pressured to try quickly. The right time is the time when you feel physically and emotionally ready.

How fertile are you after a miscarriage?

For most people, a single miscarriage does not prevent them from becoming pregnant again, and most women who have had a miscarriage go on to have a successful pregnancy in the future.¹

A miscarriage can, however, be followed by a slightly higher risk of another miscarriage. That doesn't mean another loss is likely to happen, and the risk generally decreases after a subsequent successful pregnancy.³

It's also important to distinguish miscarriage from recurrent miscarriage. In the UK, the NHS advises speaking to your GP if you've had 3 or more miscarriages, when you'll usually be offered further assessment to look for a possible cause.¹ Your doctor may recommend assessment earlier depending on your individual circumstances.

When are you fertile after a miscarriage?

Ovulation can return before your first period after a miscarriage. That means you can become pregnant without having had a period first.¹ 

Your next period may take up to 8 weeks to return, and it can take a few months for your cycle to settle back into its usual pattern.¹ Some NHS services give a typical timeframe of around 4 to 6 weeks for the first period.³

Once your cycle has settled, the fertile part of your cycle works in broadly the same way as before. Ovulation usually happens around 14 days before your next period, although this varies from person to person and from cycle to cycle.

If you're not ready to try again, this is worth bearing in mind. Because ovulation can happen before your first period, you can become pregnant sooner than you might expect. If you don't want another pregnancy yet, use contraception when you resume sex.

How soon after a miscarriage can you get pregnant?

For an uncomplicated early miscarriage, there is usually no medical requirement to wait for a particular number of months before trying again. The NHS says you can try to get pregnant again when you feel ready, after your miscarriage symptoms have gone.¹

You don't necessarily have to wait for your next period either. Research has not found that conceiving before the first post-miscarriage period increases the risk of another miscarriage or adverse pregnancy outcomes.

There are a couple of practical things worth keeping in mind first:

Give your body time to recover. The NHS advises not having sex until your miscarriage symptoms have gone because of the risk of infection. Some NHS pregnancy services advise waiting until bleeding has stopped before resuming intercourse.³

Follow your pregnancy unit's advice about pregnancy testing. Depending on how your miscarriage was managed, you may be asked to take a pregnancy test around 3 weeks afterwards. A positive result can sometimes indicate that pregnancy tissue remains and needs further assessment.

You don't have to wait for one normal period. Some clinicians and NHS services suggest waiting for one period because it can make dating a subsequent pregnancy easier.
There can be exceptions. If you've had a pregnancy outside the womb, such as an ectopic pregnancy, or a molar pregnancy (hydatidiform mole), your care team may advise waiting longer before trying again. The timing can depend on the treatment you received and, in the case of a molar pregnancy, follow-up hormone monitoring. If either applies to you, follow the advice from your specialist team.

Is it easier to get pregnant after a miscarriage?

It's a common question, and an understandable one. The honest answer is: a miscarriage doesn't appear to create a fertility boost, but it also doesn't usually prevent you from conceiving again.

Some large observational studies have actually found slightly lower fecundability after a previous miscarriage. One Norwegian study involving more than 48,000 planned pregnancies found that fecundability was lower among women with one or more previous miscarriages.⁶ A Danish prospective study found a similar pattern, although women with a previous miscarriage had a broadly similar cumulative probability of pregnancy by 12 cycles of trying.⁷

So it's more accurate to say that a single miscarriage does not usually cause an ongoing fertility problem, rather than saying it makes conception no harder than before.

What can genuinely help your chances, whenever you decide to try, is looking after the basics before pregnancy:

Folic acid. The NHS recommends taking 400 micrograms daily before pregnancy and through the first 12 weeks. Some people are advised to take a higher prescribed dose, such as 5 mg, depending on their individual circumstances.⁵

A healthy weight. Being significantly underweight or living with obesity can affect fertility and pregnancy health.

Caffeine. Keeping caffeine to no more than 200 mg a day is recommended during pregnancy and is a sensible limit when you're preparing for pregnancy

Smoking and alcohol. Stopping smoking and avoiding alcohol when trying to conceive and during pregnancy can support a healthier pregnancy and reduce pregnancy risks.

MMR and rubella immunity. If you're not immune to rubella, speak to your GP about MMR vaccination before pregnancy. Leeds Teaching Hospitals advises avoiding pregnancy for one month after the MMR vaccine.

For couples where the woman is under 40, the NHS says that more than 8 in 10 will conceive naturally within a year if they have regular unprotected sex every 2 to 3 days. A previous miscarriage doesn't mean you should assume you'll have difficulty conceiving.

Trying to conceive after a miscarriage

There's no "right" time to try again. Some people feel ready within weeks. Others need months, and that's just as valid. The NHS advises that you can try again when you're ready and your miscarriage symptoms have gone.

If you'd rather wait, you may want to use contraception when you resume sex, since ovulation can return before your first period. Condoms can be used when you resume sexual activity. Other contraceptive methods can also be started after miscarriage, depending on the method and your circumstances.

If you've had a previous miscarriage and experience bleeding in a future early pregnancy, speak to your GP or early pregnancy unit. NICE recommends offering vaginal micronised progesterone 400 mg twice daily when a scan has confirmed that the pregnancy is inside the womb and there is early-pregnancy bleeding alongside a history of miscarriage. If a fetal heartbeat is confirmed, NICE recommends continuing treatment until 16 completed weeks of pregnancy.⁴

This recommendation is specific: NICE found evidence of benefit when there is both a previous miscarriage and bleeding in the current early pregnancy. It does not recommend progesterone simply because someone has had a previous miscarriage without bleeding.

Above all, be patient with yourself. It's completely normal to feel anxious about trying again, particularly around the time of year you lost your pregnancy. Talking to your partner, a GP, counsellor, or a support service such as the Miscarriage Association or Tommy's can help you feel less alone with it.¹

How twoplus can support you as you try again

Trying to conceive after a miscarriage often comes with more emotional weight than trying for the first time. Every cycle can feel loaded with hope and worry in equal measure. Some couples find that having a bit more control over the process, without turning every attempt into a clinical appointment, helps take some of the pressure off.

This is where the twoplus Applicator can fit in. It's designed to deposit sperm close to the cervix, at home, in a way that's private and unhurried. It isn't a treatment and it isn't a replacement for medical care. If you've had recurrent miscarriages or you're already under a fertility specialist, it's worth discussing with your GP how the Applicator might fit alongside any advice you've been given. For many couples simply trying again after a single loss, it can be a comfortable, low-pressure option to consider before or alongside other steps like IUI or IVF.

The Applicator is a consumer fertility aid rather than a medical fertility treatment, so it shouldn't be viewed as equivalent to IUI or IVF. If you have an underlying fertility problem or recurrent pregnancy loss, medical assessment remains important.

Trying again doesn't have to feel clinical

Whatever stage you're at, going gently with yourself matters just as much as the practical side. The Applicator is one small part of that: a way to try for a baby on your own terms, in your own space, while you and your GP keep an eye on the bigger picture together.

FAQs

Do I need to wait for a period before trying again?

No, not medically for an uncomplicated early miscarriage. The NHS says you can try again when you feel ready and your miscarriage symptoms have gone. Some people choose to wait for one period because it can make a future pregnancy easier to date, but you can conceive before this.

Can I get pregnant before my first period after a miscarriage?

Yes. Ovulation can happen before your period returns, so it's possible to conceive without having had a period first.

Does a miscarriage mean something is wrong with my fertility?

Not usually. A single miscarriage is common and most women who have one go on to have a successful pregnancy.¹ Some studies have found slightly lower fecundability after miscarriage, but this does not mean that most people will have an ongoing fertility problem.

How many miscarriages before I need tests?

In the UK, the NHS generally recommends speaking to your GP after 3 or more miscarriages, when you'll usually be referred for further assessment. Your GP may recommend seeking advice sooner depending on your age, medical history or individual circumstances.

Is progesterone recommended after a miscarriage?

Not simply because you've had a miscarriage. NICE recommends vaginal micronised progesterone for women with a previous miscarriage who have bleeding in an early pregnancy and have a scan-confirmed intrauterine pregnancy.

Is it normal to feel anxious about trying again?

Completely. Pregnancy after loss can bring a mixture of hope and anxiety. If you're struggling emotionally, speak to your GP, pregnancy unit, counsellor or a pregnancy-loss support organisation.

When should I speak to my GP about difficulty conceiving?

The NHS advises seeing your GP if you have not conceived after a year of regular unprotected sex if you're under 40. You should seek advice sooner if you're aged 36 or over or if there's another reason to be concerned about your fertility, such as a known fertility problem or certain medical conditions.
