First of all, girl why are u with him if he hits u? I'm not here to judge, but I am concerned for you. You're only 17, there is so much more. I dont' think u wouldn't "miscarry" and know it that soon after having sex. Why didn't u think u could get preg.? U can pretty much always get preg. Any time through out your cycle. My first sugg. Would be to find someone new, and my second would be to wait until your next period b4 you get too worried. If you miss and even if you don't miss and are still concerned, then take a ept test. They have preg. Tests for only $1 at the dollar store!!!! Good luck girl.

In order to have a misscarriage you have to have concieved and since you were on your period, you did'nt. The only way to get pregnant while on you period is when the sperm lives inside of you a couple days and then you ovulate. Its impossible to have your period turn into a misscarriage! Secondly and might I add most important.....You do not need to be with someone that hits you! Why would you want to have child with someone that might harm the baby before it's even born!!! Don't be stupid and let him do this to you! I don't even know you but you deserve so much better! Don't just leave for yourself, leave for any potential children you might have~!! You don't want to have a child with a man who hits you becuase chances are he will hit the child! Get yourself something better!

Bluebubble are you sure that I can't get pregnant while on my period. I had sex the first day I was on it and still had my period for another 4 days.

Gosh I can't believe you allow him to hit you, you need to be stronger than that and not put up with that.
You should probably wait to see if you miss you're next period.

Please girl if he continues to mistreat you you have to let him go......

Yeah first of all, never ever let anyone hit you. If he has no respect for you, how is he gonna respect your children. Imagine that if you are pregnant, what he would be doing to them. It's just horrible. Please leave him, you dont deserve that kind of treatement!

Anyway, you can get pregnant while your on period, before your period, and after your period. You can get pregnant all the time anytime. I dont think it was a good idea to have sex without the condom and him finishing in you - definitely bad idea. You have a chance but i'm not saying it's definite. Take a blood test and keep us updated (:

I went through that with an abussive boyfriend and believe me hunny it is the hardest thing to get over yeah I know but you need to leave.. I left my boyfriend one day just out of the blue when he called me a b*tch and I just said that I was done and I was it was hard to get over but you want to get out of that asap believe me. The faster the better..

Ok, i'm your age, and first of all I had to deal with my mom getting beat all the time, so please do yourself a huge favor and leave that man, no women, frankly nobody should be hit, and I hope you are ok, just please get help, noone deserves to be hit, and you definetly don't need to have a baby by him!
Leave him!
