I had sex with my girlfriend two days ago... A little while ago, she called me and told me she had "abnormal" bleeding not like a period but just different. She told me her cycle wasn't to begin for another week, and she felt sick. I know the only way to know for sure is to see a OB/GYN but, are these signs more closely match of a early cycle or a pregnancy... She also has been a little more active in the last 2 weeks and has changed her diet (been eating more). I thought I wasn't that guy, but here I am that guy! Can someone confirm my concern or put my mind at ease?
