pregnancy?😭 or just stressing out?

I had sex last week with my boyfriend, I'm on birth control for 3 months now and it was my first time that guy did it inside me... it was One day before my fertile window ended. I know I might be just stressing out but i feel a bit strange feeling around where my right ovary should be... is it normal? Is there a chance that my pills wouldn't work? I'm just so freaked out.Â
