Oh by the way you are down as male in your profile shouldn't that be female??
Hi there
You didn't say how long your period was??
So I am guessing here as need more information really but if for instance you were on a 28 day cycle????
And your period lasted 7 days .
You had sex on day 9
your fertile days would be day 9 to day 15
So even though he pulled out normally guys release some sperm before fully ejaculating so it is possible you could get pregnant yes.
If you are at all worried and don't want to be pregnant you can get an emergency morning after pill which can be taken up to a couple of days after you had sex .
Hope this helps xx
Let us know how you get on
