I had sex and he comes in me I took a plan b the day after. A week later he comes in me again and I don’t take a plan b, I get my period . A couple weeks after that he comes in me again and I take a plan b. I got my period on the 17 of the last month , it is now the 17 . I took a pregnancy test two weeks after he comes in me and it was NEGGATIVE. I have never felt like throwing up so much and I threw up all my alcohol when I drank some and I have never thrown up before while being drunk. What should I do ?
