blissful, i am sure ur doc has reviewed ur blood tests results etc before deciding on this protocol. So dun worry. Actually initially mine was not on microgynon, because based on my earlier bloodtest (done almost 1 year ago before i start fresh), my hormones are normal. I did another BT just before i start my fresh cycle and the bloodtests results shows otherwise. so i was prescribed microgynon. and at least u r sure ur menses will come during lucrin stage. Else during lucrin, if u r stressed, the menses didn't come, u may get more worried.
