Am I tweaking too hard

I had sex like over two weeks ago. Condom, no ejaculation at all. No birth control at the time. I went to the gyno last Monday to get put on the pill. I got my period at the regular time. She said she wasn't gonna have me take a pregnancy test since I was on my period. I am somehow still worried. Am I overreacting ? Sorry, I know that pretty much every other post is like this but whatever man. I just want someone else's opinion.
