I'm 6dpo and I had unprotected sex 3x during ovulation. Last night I had really bad stomach cramps and sorry if this is TMI but I had diarreha while feeling like I had to vomit at the same time. I was dizzy, shaky and was sweating. I thought it was food poisoning, but it didn't last very long. Not sure if anyone else has ever had this or what, but any thoughts?!
