UGHHHH IM SO WORRIED😩

Took plan b on the 27th same day I had sex. Next day started with nausea. Two weeks after sex and plan b I started bleeding with some clots for 5 days. Which is when my period was due. Fast forward to this week Yesterday was my ovulation and I’ve been so nauseous and having cramping on my left ovary. I’m set to start my period in 12 days but of course knowing plan b isn’t 100% I’m extremely paranoid and anxious making me nausea worse.

Also he didn’t cum in just pull out BUT I know precum is also a risk. What do you all think?
