I was on the mirena and breastfeeding for two years and had no cycle. I had the mirena taken out and and had a period about 5 weeks later. Stopped breastfeeding and had another period 28 days later. But now i have not had a a period for almost 3 months! Pregnancy test negative. I phoned the doctors and was told to come in for a blood pregnancy test. When that was negative (dr secretary said it looks like my body is trying hard to ovulate) I was told to come in for further blood tests , to check hormones etc. I got a call to say it looked fine, and i should come in after the new year if still no period or pregnancy test.
i feel completely in the dark,when not on mirena i have always had extremely regular period.
