Really i have two questions, My girl friend has been on the same birth control for about a year and a half, We have sex consistantly, at least once a day if not every other for the last 3 months. Her periods are always regular, and on time. However, She had a random dark red/brown discharge 4 days before her period for a about a day and half. then it went away, i read it may be from ovulation, however, we don't know when she ovulating, how can you tell.
Well can't say for sure if it is related to ovulation, but ovulation generally occurs around the 14th day from her first day of period, well around that time mostly!! some people might have some cramps around that time!! so usually they say the first four days on either side of ovulation is unsafe!! well i hope this helps :-)
