So April 10th me and my boyfriend didn't have sex but we played around. I am on birth control. I got my period the 17th of may. But I still got a pt , and it was negative. But on the 28th of may I got something very very close to a period that lasted 7 days and then skipped one and started again. I had no symptoms of being pregnant, but the line on my belly is brown and my nipples are changing colors. But they say that can be caused my hormonal imbalance and from being in because. But today we and my boyfriend were playing around and he was giving me oral and I noticed after that I was bleeding and it was not light. Does anybody understand what maybe going? I go to the doctor this Thursday, and I am very scared. My mom does not know about the things me and my boyfriend are doing.

Funny thing, stress causes irregularities in menstrual cycles. So, your initial stress might be causing it to be delayed farther. Just relax. If you're getting checked by a doctor, they'll find the issue.
Not to mention, if you're not actually having intercourse, you can't get pregnant.
Oh, and just so you know, if you're pregnant, you'll almost definitely know. When women become pregnant, they're whole body chemistry changes. You're senses heighten. So, at least now you know the signs..

Thanks.
