Pregnant while on the pill


Sooo yesterday I had a dr appointment because I had been having some issues with painful intercourse so I wanted to get checked out and plus well I hadn’t had a period since March but I had taken a test a week after my missed period (2 test ) and came out negative 🤔 so this morning the nurse calls me and tells me my pregnancy test came back positive!! I was in complete shock to say the least . I started crying cuz well I already have a 2 yr old and a 1 yr old and a 9 yr old . I took my pill EVERY NIGHT ! Has this happened to anyone ? I just need words of encouragement 😏
