Had this fitted in July. It's great. But... I have pcos so my cycle has always been long. I often skip periods, that's normal for me. Has been this way for 20 plus years. I've still managed to have 3 babies. Anyway, since coil was fitted my cycle has reduced to 25 days and each period is heavy and lasts up to 10 days. At one point I had 3 periods in 6 weeks. Also had awful pelvic pain, still experience this several times a month. Any one else had such a dramatic change in their cycle? Didn't expect this. Had a scan which showed small cysts on ovaries.
