My finance and I live together and are both still in college. I have the implanon implant not for birth control. We don't ever use protection and he doesn't always "pull out" so I was wondering if you can still get pregnant while in this birth control or how likely is it. I am wondering because I have been not feeling well the last couple of mornings and my nipples are very sore. I am just wondering if it is like post period sickness or a possible pregnancy
