Hi.
I'm currently doing an extended contraceptive patch cycle, as recommended by a health professional. They told me to keep the patch for three months and then remove.
I've had it on for almost four weeks, and a few days ago breakthrough/withdrawal bleeding started. Is this bleeding entirely normal and happening because the uterus has not shed its lining in about a month and because it sloughs off, as it thins? Is it normal to bleed while the patch is on? Should I continue with putting on a new patch every week and am I protected from pregnancy?
