I’ve been on birth control pills for exactly half a year now. The longer I’m on them the longer it seems to take for my period to come. It’s supposed to happen the last week of the pills. It used to start on the first non hormonal pill but migrated and now I’m almost done with this week and still no period. I’m a little worried because I’ve been having sex as well, we use condoms and pull out. It’s just a weird situation, any help?
