It’s not likely, but it is possible. Your chances of getting pregnant just after your period depend on how short your menstrual cycle is, and how long your period lasts.

One of your ovaries will release an egg (ovulation) about 14 days before your period starts. The first day of your period, when you start bleeding, is counted as the first day of your cycle. If you have a 28-day cycle, you’ll usually ovulate some time between day 10 and day 15 of your cycle.

During your period an egg is usually developing, ready for release mid-cycle. The time it takes for an egg to mature within the ovary can vary. This means that the day you ovulate can also vary from cycle to cycle.

Having a short cycle and a longer period could increase your likelihood of getting pregnant just after your period. If your cycle is short, 22 days for example, then you could ovulate just days after your period, if your period lasted seven days. The longest that sperm can survive in fertile cervical mucus is seven days. So it may just be possible for you to get pregnant if you ovulate a little earlier than usual.

However, it is more likely that sperm will have a life span of two to three days, even less if there is no fertile cervical fluid. Most pregnancies happen after sex within the five days before, and on the day of, ovulation.

To conceive, your egg needs to be fertilised within 12 hours to 24 hours of ovulation.

It’s also possible to mistake breakthrough bleeding, which is spotting between your periods, for a regular period. So you could experience bleeding during your fertile time. If you are experiencing bleeding between your periods, you should tell your GP.

Whats the chances of getting pregnant right after your period

The short answer? While not likely (you typically still have to wait a bit for the ovulation process to kick in), it’s entirely possible.

If you’re trying to conceive, the answer to the question when’s the best time to get pregnant after your period? might feel like it’s taking up a whole lot of real estate in your mind.

When do you ovulate after a period?

So how many days after your period do you ovulate?


This is a hard one to answer because periods – and the cycles of which they’re a part – are all different lengths, because, after all, we’re all different!

So, that means that ovulation after periods will be different, too.

Do you ovulate before or after your period?

A general rule of thumb is that you will ovulate 10 to 14 days before your next period.

(Remember the part about your period being the going away party for an unfertilized egg? Yup. That’s how long the egg gets to stick around for until it is not so politely asked to leave.)

If you’re wanting to conceive, it might be a good idea to start tracking your monthly rhythms so that you can feel a little more in the driver’s seat of all of your bodily shenanigans.

Can you ovulate right after your period?

Typically, you don’t start ovulating straight after your period, although some people do have shorter menstrual cycles.

So, some people with shorter cycles might start ovulating 6 days after the first day of their period ‒ and if your period lasts around 3-4 days, you could start ovulating within a couple of days of your period.

Can you get pregnant after your period?

In a word: yes.

Think of your menstrual cycle starting on day one of your period, and lasting for roughly 28 days (although some people’s cycles can last between 21 to 45 days, as well).

Typically, you’ll start ovulating in the middle of your cycle.

So it depends on how long your period lasts as to whether you start ovulating right after.

Plus, you can get pregnant any time from 5 days before ovulation to 1 day after ovulation.

Considering ovulation usually lasts for 1 day, that gives you about 7 days during your menstrual cycle that you can get pregnant.

However, there’s no guarantee that you will (or won’t) get pregnant outside of these days.

How soon after your period can you get pregnant?

You can get pregnant straight after your period, although the chances are pretty slim.

However, you’ll likely be at your most fertile (ovulating) about 7-16 days after day 1 of your period (the start of your menstrual cycle).

How many days after your period can you get pregnant?

But just how long after your period can you get pregnant?

When’s the best time to get pregnant after your period?

So, it’s time for the “how to get pregnant after period” portion of our guide.

The funny thing is, for all the procreating we do as a species – it must be fun or something – women can only get pregnant during a pretty small chapter of every month.

The fertile window, as it’s called, is a small one.

So if you’re wanting to know if you can get pregnant after your period, yes you can, but typically a few weeks after.

The fertility cycle is about 6-10 days in most women.

If you’re the cookie-cutter textbook 28-day regular cycle case, this would be around days 10-17 of your cycle.

That’s why many couples land up getting a fantastic toolkit of calendars and clocks – and sometimes even canceling important engagements – to, well, get it on.

But of course, in the chimeric world of what is typical, very little is. In fact, in only about 30% of women is the fertile window entirely within the days set out by the clinical guidelines

Can you get pregnant on your period?

While you can generally consider this a pretty safe zone, surprises of all sorts find their way into the fertility story.

It’s a little something like this. Remember playing tag as a kid? (Bear with us.)

Well, in this popular children’s game, there is typically a safe zone, or “den”, where, as a player, you’re free from being tagged. Sure, this space is safe.

But remember: there’s always that one “it” who doesn’t play by the rules and tags you anyway.

The most important thing to remember: sperm can survive in the body for up to 7 days after you have sex.

So if you ovulate early or have a naturally short cycle, it’s possible.

Because life’s like that sometimes.

In summary:

  • There’s a window of fertility, and usually, your period likes to hang out in other parts of the month.
  • Tracking your own unique cycle may be useful if you’re looking to conceive.
  • If you’re looking to stay as far away from conceiving as possible, your period may present a safer zone, but safer is by no means totally safe and should be treated accordingly.

So that’s all you need to know about whether you can get pregnant right after your period!
