i am on the birth controle, marina.. i have been on it for about 10 months now, i just recently started to get stomach pains, only lasting about a min then going away, i have been feeling dizzy, like i dont have enough iron (i only felt this way when i was pregnant). i have had some blood spots, but only like two or three a day, All this Seems to happen more if i have entercourse. also i have had like dark brown bloode come out. could this be from a problem with the birth controle?
