I finished my 7 pill free days as you do and had my period it's been over a week now and I'm back to normal on my new strip but I've missed four pills as the doctor is trying to see if stopping my yasmin helps my migraines but I woke up this morning to quite bad fresh blood? Is this normal as I've finished my period over a week ago but during this time I have had intercourse while I've missed my pill using the withdrawal method :/.
