Ok, so I’m on birth control pills and before I finished the active hormone part of the pack I started to bleed. I usually get my period on the 20th but it started early on the 17th. Today is the first day I’ve taken the non hormonal part of the pack and still bleeding as if I have my period but no cramps. Has this ever happened to anyone? I’ve been on BC for several years and this has never happened to me before.
