I having a problem down there!!HELP!

about two weeks ago I started bleeding... I first thought it was my period so it didn't bother me. Well after having my "period" for two weeks I got a little worried... well it stopped for about two days...then it started again... I don't know what's wrong... about three months ago I started birth control but I'm not sure if it a side affect or something. also, I also have like milk lumps under my nipples in my breasts. I know its not breast cancer , at least I hope its not. I have this in both but I'm not sure what it is! PLEASE HELP!
