<s>[INST] Hello, I had the IUD mirena for 3 years then about a little over than a year ago i got it removed.I haven t been on any birth control since I rarely get a period, like one every 2or 3 months ( or even longer, and i have not gotten pregnant . Dose this happen ?? [/INST] hi! thanks for choosing healthcaremagic.com.Usually as soon as the iud is removed there is a return to normal periods,incase of hormonal iuds it takes upto an year to get periods regularized.Do get a scan done to see if your uterus,endometrium,ovaries are otherwise normal,no cysts etc,.Cycles have to be regularized ,ovulation has to occur only then canyou conceive, </s>
