So I need your advice, I finished my period on the 3rd of June and have had unprotected sex 3-4 times since, I'm not supposed to be fertile yet, but I feel like I might have ovulated really early, anyway, since this morning have been really badly nauseous and haven't really been able to eat, now I don't know if I could even possibly be nauseous this early or not, but I can't pick why I would be otherwise, so anyone else had nausea really early on?
