HI,am 26 years old and am married for d past 7 years now but without a baby,although my Docs have comfirmed to me that i've PCOS,i've tried 1 IUI,1 IVF,1 FET.My major problem now is my period is becoming more irregular,unlike before my period usually comes back after three month,but now i dont 've a specific date and is been like that about 2 and a half years now,and i've to be taken primolut n each time i want my period back.last two weeks i took primolut n for 5 days twice a day,and up till now i didnt see my period,could that be that am resistant to primolut n,or could it be the effects of the IVF/FET drugs and shots? or could i be pregnant without knowing i am??? PLEASE am confuse. thank you alot.
