Ok, so about a week ago my boyfriend and I were fooling around and he ended up rubbing his penis on my vagina and inserting the tip in for about 10 seconds, unprotected. I know that was stupid, but he never came. It was only precum, we know this for a fact. Now today, I was scheduled for my period and also the day that implantation bleeding could occur if I was pregnant . I noticed a little regular, red blood spotting and got excited because I was scared that I was pregnant and thought I was getting my period. But I used the bathroom a few minutes ago, and I found no blood. Then I recently read into implantation bleeding and now I m scared out of my wits. I CAN NOT be pregnant. I m so scared. Last night, I began to cramp. And I also read that implantation can cause cramps . OF COURSE! It s makes me so aggravated. I m so scared.
