I MESSED UP!!!!🤕🤕

I took PLAN B last month because I had unprotected sex and I was scared so I took it. I did get my period the day of .. but now I had sex today but with a condom and without at times but most of the times with a condom. I took a shower right away but now I'm scared. My bf was DRYYYYYYY😐 like no cum nothing. I'm determined that next time is WITH CONDOM alone ... should I take Plan B again ... and my fertile window closes in 3 days ... should I be worried 🤕
