i had protected sex with my boyfriend on friday nov 8 but the condom broke. not entirely sure if he finished inside me or not. immediately we went to go buy plan b since i am not on any form of birth control. i took the pill within 20 minutes of having sex. my other tracker app said that it was not one of my ‘fertile’ days but it was a few days after ovulation. will the pill still be effective? i am expecting my period tomorrow at the earliest. i have been feeling some cramping, headaches, and back pain. not sure if from the pill or what. im so stressed out
