Ive let my husband finish inside for the past year and ive taken my birth control everyday at the same time im on Junel 1.5/30 . No pregnancy scares. I always check once a month a pregnancy test just to be sure but nothing. (knock on wood 🤣) As long as you take it daily at the right times, you should be fine! But, if you feel scared then do what other women do with condoms for extra protection.
