Skipped 2 BC pills 🙊pregnant?? 🤷🏻‍♀️

Li

I started my 1st pack of birth control on November 26. And I skipped 2 days of birth control! December 8 & 9. And my SO didn't pull out on December 8. On December 10th i took my pills that I missed. Anyway I suppose to start my period on Sunday. And I still haven't gotten it yet and it's Tuesday! My boobs hurt! I'm cramping and I have the worst headaches I ever had!! Idk what to do! When should I test?
