Hi my period is 2 weeks late and I'm scared that I might be pregnant. I had unprotected sex but my boyfriend didn't inside me and he didn't even finish at all because we stopped because I was afraid of possibly getting pregnant. That happened the day I was supposed to get my period. My last period was only 4 days which was unusual for me because usually I have it for a full 7 days. I have taken 2 pregnancy test and they both said negative but today I got a brownish/ yellowish discharge and I'm afraid it might be implantation bleeding. I'm very confused on if I am pregnant or not. Any advice?:(
