So I had sexual intercourse last night and I am on my period the condom didn't break but it sliped up a bit and I was wondering if I had a chance of being pregnant. We checked very carefully and there were no holes, but I am not on the pill and I was wondering if I might be pregnant thanks:)

It sliped? Enough for cemin to come out and enter you? And if so its hard to tell at this moment.. Only time could tell.

Chances are no, you are not since you are on your period. However it only takes one egg and one sperm to meet up. If you had intercourse last night, the sperm has not met up with the egg yet. This takes about 3 days after intercourse for the two to meet.

Unfortunately you are now playing the waiting game and have to wait until your next period is due. If you don't want to be pregnant you can get the morning after pill. Has to be taken within 72 hours after intercourse.
