HELP!!!!

Just had intercourse Sunday night to Monday morning (yesterday). He came in me 5 times throughout the night/morning. I know I shouldn’t have let him if I didn’t want to get pregnant. Don’t need y’all to shame me on that.🤦🏻‍♀️ I’m supposed to get my period in 6 days. I took a plan b yesterday but I also weigh 300 lbs. Will the plan b work? Am I getting pregnant? I need insight and advice.😭😭😭😭😭
