Whether you’re TTC or trying not to have a baby, the question on everyone’s mind is: Can you get pregnant right before your period?
Are there any subjects more puzzling than pregnancy and periods? We doubt it.
When you’re trying to conceive, it can feel like questions about pregnancy, periods, and everything inbetween dominate your life.
Can you get pregnant right before your period? Can you get pregnant a week before your period? Can you get pregnant on your period, for that matter?
Sheesh. It’s just exhausting. Period.
So that’s the plan here ‒ to finally get to the bottom of these questions. Here goes:

Can I get pregnant right before my period? We hear you ask. Well…
Because our bodies love a gray area, the short answer is: possible, but highly unlikely.
When you look at all the people on the planet, it’s pretty hard to imagine that conception can actually only take place in a tiny little monthly window that typically only lasts about 6 days.
After all, there are mamas and pregnant people on Peanut who have stories like “I got pregnant a week before my period” or “I got pregnant 1 day before my period”.
But, ‘typically’ speaking, most people get pregnant in the lead up to, during, and after ovulation ‒ when your hormones get an egg to release from your ovary.
To get pregnant, that egg needs to hook up with some sperm – and fast.
As in 1224 hours after ovulation kind of fast.



Ovulation usually happens at about exactly the opposite corner of the month to your period.
(At this point, we’ll just irritatingly remind you that, for all the painful symptoms, your period is simply your body getting rid of the egg that didn’t swipe right on any sperm that month.)
That’s why, typically at least, the likelihood of pregnancy right before your period is not great.
(And if you’re asking can you get pregnant on your period? – the same answer applies.)
Can you get pregnant before ovulation?
While that would be rather miraculous, there is a possible plot twist that could land you with a positive pregnancy test when you’re not in what you think is your ovulation phase.
Even if you have a cycle that is more predictable than a badlywritten soap opera, there is a chance that your fertile period may not be that obvious.
There are longer and shorter cycles with all sorts of factors like age, stress levels, and just plain genetic makeup that pop in to mess up the predictability of your fertility window – all things you need to try your best to get in touch with if your plan is to conceive.
But then, of course, your plan might be to not have a baby right now, or ever, and that’s totally valid.
If that’s the case, there are lots of different forms of birth control that may be available to you ‒ whatever works for you!
Do you ovulate before or after your period?
Look, your fertile window is only about 7 to 10 days, so technically everything outside of that time should be a safe zone. Technically.
But how many days are you likely to get pregnant right before period?
Can you get pregnant a week before your period, or can you get pregnant the day before your period?
Let’s look at the chances of getting pregnant right before period.
It is possible to get pregnant before period ‒ or at any point in your menstrual cycle.
Here are the chances of getting pregnant during a ‘typical’ menstrual cycle:
 Day 1: Less than 1% chance of getting pregnant (first day of period)
 Day 2: Less than 1% chance of getting pregnant
 Day 3: Less than 1% chance of getting pregnant
 Day 4: Less than 1% chance of getting pregnant
 Day 5: Less than 1% chance of getting pregnant
 Day 6: Less than 1% chance of getting pregnant
 Day 7: Around 3% chance of getting pregnant
 Day 8: Around 6% chance of getting pregnant
 Day 9: Around 9% chance of getting pregnant
 Day 10: Around 18% chance of getting pregnant
 Day 11: Around 27% chance of getting pregnant
 Day 12: Around 33% chance of getting pregnant
 Day 13: Around 42% chance of getting pregnant
 Day 14: Around 20% chance of getting pregnant (ovulation day)
 Day 15: Around 8% chance of getting pregnant
 Day 16: Less than 1% chance of getting pregnant
 Day 17: Less than 1% chance of getting pregnant
 Day 18: Less than 1% chance of getting pregnant
 Day 19: Less than 1% chance of getting pregnant
 Day 20: Less than 1% chance of getting pregnant
 Day 21: Less than 1% chance of getting pregnant
 Day 22: Less than 1% chance of getting pregnant
 Day 23: Less than 1% chance of getting pregnant
 Day 24: Less than 1% chance of getting pregnant
 Day 25: Less than 1% chance of getting pregnant
 Day 26: Less than 1% chance of getting pregnant
 Day 27: Less than 1% chance of getting pregnant
 Day 28: Less than 1% chance of getting pregnant
However, menstrual cycles can last anywhere between 21 and 45 days, so your individual days of ovulation and chances of getting pregnant before period might be different, but you can use this as a guide.
