hi im 20 years old. i have a 9 month old son. when he was 3 months i was given birth control pills for breastfeeding by my ob. i took it for 3 months and stop taking it for 2-4 months. i was away and wasnt able to get more. anyways i got my refills and it was a diff. kind of pills. on aug. 1st i had my period. last about a week. another week past, the following week i bled again. thinking it was probably the change of the pills thats affecting my body. then the next next week im bleeding again. i had intercourse the day before i bled. we didnt use a condom, it didnt last that long. i mean is this okay or normal? a sign of diff. pills? please help
