Possibly Pregnant?

Please bare with me, I know these get annoying and I never thought I’d have to write one myself. I am on Tri-Previfem. I have been on this exact brand for a month and a half now (was on tri-sprintec) I don’t take it at one designated time but I always take it before I go to sleep. My boyfriend and I had unprotected sex for the first time exactly a week after starting this pack. He pulled out but there’s still a chance some came out I know. I keep having weird feelings in my stomach and my ovaries hurt when I sneeze (weird I know, but a supposable effect of pregnancy). Am I just freaking the hell out for no reason? Does taking the pill at different hours really affect it that much?
