question: For about two months now Ive been having nausea. Sometimes it will last all day, some days its sporadic, and lately its been happening when Im aroused or after I masturbate. Along with the nausea Ive been having pains in my lower abdomen around where my uterus is (almost like mild cramps as my cramps are severe). At first I thought I was pregnant because Id had unprotected sex with my boyfriend twice. But the last time I took a pregnancy test it was 6 weeks after the last time wed had sex. Wouldnt it have shown if I was pregnant? What could be wrong?
