Hi, I Had Unprotected Sex On A Sunday, While I

Hi, I had unprotected sex on a Sunday, while I was on period (please don't judge), I had the unprotected sex around 1:30 am on Sunday and couple hours later had sex that same day again I'd say like around 3:00. And I took the "my way" pill like a plan b on a Tuesday morning. Could I be pregnant? I'm also ok birthday control but just wanted to take the my way to be extra safe. And now my stomach feels kind of bloated and wanted to know if that's normal. Please help me I'm too young to be pregnant
