Okay, so i had my period and 2 days after my period ended me and my boyfriend had sex. Now being 4 days since we had sex, i am bleeding and i have some mild cramps. I am wanting to know if I am pregnant? Im not bleeding too bad its not like its a ton, its just mild. If i didn't have my period a week ago, i would think i was just starting it right now. Is it normal to bleed? I am irregular and this hasn't happened before.
