that could mean that you are. That is what happened o one of my friends a few days after she had had sex she had gottin her period but it didnt last long maybe like a day and then he found out that, that happens to a lot of people that are. I am not a mom but I know how this stuff works I had to take parent child development for my job. hope it helped
