I had to stop my last pack on Jan. 25th because I had missed two of the white pills but just started my next pack on Feb. 17th. I haven't had my period yet but I've read on the internet that missing a period when you go off and get back on can occur. And another side note, the next week after stopping I had spotting (which I heard is common with stopping a pack). I haven't had any vaginal sex with my boyfriend and we are both very certain that nothing has come in contact with any of my parts. Should I be worried or is it normal to miss a period if you have to stop a pack?
