A couple uh oh’s

My overthinking gets the best of me so I’m sorry if I sound silly! I’m on the pill and this month I started a new pack. On the third day taking them I had unprotected sex. The next day I forgot to take one so I doubled the next day and had unprotected sex that night. I believe I’m fine but there’s a little fear in me since I had a miscarriage 2 years ago when I wasn’t planning on getting pregnant. Help ease my mind?
