So my period came on May 29, and went off 4 days later. I had unprotected sex on the 3rd of June . I don't know if I'm stressing myself out, or if I'm really pregnant, but I've been feeling horrible. I'm just scared, because I have rough pregnancies, I have hyperemesis gravidarum, also known as extreme nausea during pregnancy. I'm so overwhelmed... The pregnancy tests that I took are negative(took 6 test), but should I take another this week, or just go to the doctor?
