Hi, I m 16 years old. I had unprotected sex a week or so before my period. Now I ve had two regular periods. I don t know if I m pregnant or sick. I vomit in the morning, I have abdominal pain, cramps, and I get dizzy. The thing is that I ve been sick before with those symptoms. But I also vomit in the afternoon, and I ve heard for pregnancy it s only morning sickness, so I don t know what to think. What s the chances that I m pregnant or sick? My ex-boyfriend said he didn t ejaculate in me, but I read online about pre-ejaculation. I m really freaking out. Help. Thanks.
