For the past week and a half I've been very tired, moody and been peeing way too much like every half hour to an hour. My bf and I have had unprotected sex last week which I believe was when I was ovulating but I'm on the pill also a few times I skipped a day but took it the next morning. My period isn't due until next Thursday. And for past few days I started getting nauseous and extremely hungry and crampy with some pain.
