This morning I took the first white pill so as to start my period. That was over 8 hours ago and I have still not even started to spot. Is this normal? I am on the every-three-months schedule to have a period, so it's been awhile. Also, I have never missed a dose, and take it at the same time every day. Is it normal to NOT start my period on the first day of NOT taking the blue pills? Thanks.
