My boyfriend an I are trying for a baby. I ovulated a few days ago. We have unprotected sex on a daily basis. The last 3 days I have felt so nauseas, light headed, weak, pukey, and my stomach really hurts. Anytime I try to eat anything it takes everything out of me and I feel fuzzy an dizzy. It's getting harder to sleep at night because I constantly feelig like I'm gonna puke. Am I pregnant? Or what could be wrong?
