Hi this is a birth control question, I been on brith control novynette for years but i been taking on the 6th day of my period but it suppose to be the 8th day, last month i took it from the 8th day and my period came 3 days after i finish the pack, this month the 3rd day was yesterday but no period why is that??? I must say i did have sexual intercourse 2 months ago but I've had my period the month after and last month it was normal heavy, blood cluts and pain as usual so can you help me figure out whats the cause for no period now?
