I've been prescribed othotricyclen-lo for my acne. My doctor asked me when I would begin my period and I said that it should be any day now. This was about a week and a half ago. She wanted me to be a sunday starter, but I still haven't started my period and I really want to start the pills! I skip my period every couple of months (i'm still not completely regular and i'm sure the pills will help out with this as well), but I don't want to wait another full month to begin! Will it be okay to go ahead and begin them since I should be having my period right now, or do I really have to wait for it to come?
