I took plan b on the 5th of Feb and that was the first day or so of my fertile cycle. I spotted a couple of days but went away no problem. I know the pill makes your period late. It was suppose to start on the 24th. But the past few days, my body has been weird. Random nausea, headaches, food is just weird to me anymore (everything sounds unappealing to me except the things I've hated to eat my whole life) And my fiance says my mood is acting off. After checking my glow logs we had unprotected sex on the 18th. If the pill delays ovulation, could I have accidentally messed up and got pregnant? I took a test a couple days ago. Showed negative but I know it could be still too early. Any input to help my worry wart mind is appreciated.
