Me and my fiancé had a baby January 6th, Im new on birth control, I had a Sunday start on the 22nd of February and had sex with a condom on the 27th but it broke meaning I was only on the pill for 6 days, some people say the brand I'm on tri cyclen lo takes 7 days for effectiveness, also when I checked my fertile window it said I would have had to had started my period on the 11th of February for the 27th to have been a fertile day, I know that even though he pulled out immediatly after he ejaculated there is still always a chance . I'm paranoid seeing as we just had a baby in January
