Paranoid?

I’m on birth control and I’ve only taken 8 pills so far (8th day was today) and I had sex yesterday and it was a quick in and out type of thing and he didn’t ejaculate & I was the only one who was wet. My stomachs been a mess all day. Am I overreacting? Could it just be from the medicine? I have bad anxiety and I usually feel like this when I get anxious. Idk. Please help. Also it’s just like a small pain that’s been like going away during the day but when I think about it it comes right back.
