I am 23 yrs old. I have a 3 yr old son. Before my pregnancy my periods were irregular so I got on the pill to regulate them. The past 3 days I have been feeling like I'm about to start my period but every time I go to the bathroom and wipe myself and brown discharge comes out. I don't know if to take a pregnancy test. If I do and it comes out negative what should I do? My husband always pulls out so I don't think I would be pregnant. But this is so weird since I've never noticed so much brown!
