can you concieve on your period or straight after your period?

I've heard of it happening, rare but possible I'd think..

It's highly unlikely unless you have either very long periods and/or very short menstrual cycles. You are most likely to conceive approximately 14 days before your period is due.

Sorry ladies i had posted this for some women who had pm'd me saying she was confused as she was measureing two weeks ahead at a growth scan at 33 weeks she was measureing 35 weeks she asked if she concieved two weeks ealrya it will be near around her period but i had told her it would be highly unlikely too. so was getting information for her i dont know a lot but im ttc myself.

It's probably more likely she's just measuring large. Measurements aren't always spot on. Depends on fluid and how baby is laying etcSmile

Hi

Growth scans are to look for growth not for dating. Scans used for dating a pregnancy are only reliable earlier on between about 11 and 14 weeks.

So her dating scan at around 12 weeks will be the one to look at if she ovulated early.

Yes it is possible to get pregnant while you have your period, but as others here have said it is unusual.

KatAndKit · 02/03/2012 12:53

What the growth scan means is that she is having a bigger than average baby. That's all. It doesn't mean the date of conception has changed.

Dating is best done using the 12 week scan. That is the most reliable time. During the first trimester, unborn babies develop at very similar rates without much difference in size.

By the time you get to the 3rd trimester, some babies are bigger/smaller/taller/shorter/thinner/fatter than others, just as not all babies are the same size at birth and two children the same age can be very different heights.

Your friend's baby is the same size as the "average" 35 weeker. She is still 33 weeks pregnant though. With a nice big baby!

As the poster above said, these measurements are not always accurate. You read on here of lots of people who were predicted ten pound babies based on growth scans and then the baby turned out to be fairly average after all.

Hmm. This is a hunch so forgive me if I am barking up entirely the wrong tree here. Are you possibly "mummytobeagainxx" posting under a different name?

My apologies if I am wrong.

wishfulthinkingxx · 02/03/2012 13:13

Huh?? i am not mummytobe or who ever your on about lol... why you asking this ?? im really confused now

or you on about who messaged me wanting to know??? if so i dont want to say as she will be offended, i will tell her to look at these threads now so she understands.

Oh it's just there was a poster by that name, similar dates, kept posting multiple threads trying to work out when in July/August her baby could have been conceived, I believe it was a paternity issue. Whatever anyone said she still didn't believe it and kept posting new threads.

it was the xx at the end of your posting name that made me think it. But as I said, apologies if I am wrong, I have in fact answered your friend's question anyway.

wishfulthinkingxx · 02/03/2012 13:25

Nope not me im not that silly, lol.. but thats fine no worries i have told her to look at these threads now.

My SIL just had a baby boy who was conceived the day after the end of her period.

It is quite unusual but definitely possible.
