Have any of you lovely ladies ever have the mirena? I had it for 4.5 yrs and never once did I miss a period with it even when most people never have a period with it. I had my period the month I had it removed and now this month I am 4 days late for af. Yes me and my husband are ttc but it's had not knowing what's going on. How long it did take you lovely's to get regular?
