I had un protected sex twice in October. On both occasions I took the morning after pill. This resulted in some irregular bleeding which later stopped. I took my period towards the end of November and on the first day of this period I started my combined pill (microgynon 30). However, my period persisted in an on/off manner until the end of the strip when I had to come off for my 7 day break. Today is Sunday, I am due to go back on my pill again on Monday, however my period, which should have arrived on my 7 day break still has not arrived. I am very confused and worried. If anyone could help provide some clarity or has been in the same position I would love to here from you.
