I find it odd because I have not experience this before. Only recently, past 4 times my boyfriend and I had intercourse. These for times he has be the only one that has had orgasms inside of my uterus. As soon as I was done menstruating we had intercourse (at least 2 weeks ago) and I felt all of the following: I feel nauseous right after and next day, headaches, hungry yet empty, sense of diarrhea, and I can't seem to eat some types of food. I actually vomited yesterday (day before we had intercourse) and today I just feel nauseous. Is this normal or am I pregnant (doubt it) ?
