Hi I'm 21 years old. Me and my boyfriend had sex once. In August. We live far away. So I don't see him all the time. Since August. I went through a month or so of naseua. Got my period 3 times. BUT it wasn't right. It was so light. And lasted for a day. It was pinkish. Not red. Once it was a bit red. Now I haven't got my period for two almost 3 months again. I gained weight. I'm always bloated. I have IBS. But I take pills. And the doctor can't figure out why I'm still bloated. I had a blood test done to see if I'm pregnant two weeks after I had sex. It said No. I've done home tests. And they said No. But I haven't done any in a few months. Could I be pregnant?? I'm so confused...
