I have 2 sons. One was born on 7-7-2013. And the other was born on 6-29-2014. I have been on the pill now for almost a month and a half. I should have started my period this week and on monday I had some bleeding but it was brown in color and very very light which is unusual for me and it only lasted for a day and a half. I took 2 pregnancy tests yesterday and they were both negative. I never had this with my first 2 sons so I dont know if its just the birth control pills messing up my cycle. Has anyone else had this happen? I need advice!
