Okay so I'm freaking out a little bit because I'm scared that I might be pregnant. But there isn't any way I could be. The only times I've had sex between my last period and now two of them were with protection and he pulled out but the other time was without a condom (I'm not on BC) he did pull out though. That was over a month ago and I did take a pregnancy test and it was negative. I haven't started my period though and it's like 18 days late. Is there any chance I could still be pregnant?
