my IUD makes me bleed while i have sex with my boyfriend. this is a new thing i have had it in for over three years now and never had any bleeding. but now with my new boyfriend its terrible. sometimes its just a tint of blood but others its just thick and dark. some times i bleed only during sex, and other times i bleed for a day or two. any one wanna fix me lol. should i go to the obgyn? or should i wait it out and see if it stops on its own.
