When I was 19, I had my mirena coil inserted and it has been my best friend for 8 years (that's an extra 3 years longer than recommended). I had mine removed in mid April with miniumum fuss and my cycle resumed immediately. I had my first period before the end of April.

I now have a text book 28 day cycle (which I never had before), my chart tells me I'm ovulating regularly and we've been TTC for 2 months now.
