Hi,
I too am ttc #3, I had my merina coil removed 2 months ago, so don't know how long it'll take this time, as I 've read that the amount of time fertility returns varies enormously from one month to eight, nine or even more! I'm sure that the same can be said for the mini pill, regardless of whether you were ovulating or not, cos it does weird things to your uterine lining!
Know it's not much consolation, but sure it will happen for you soon. Lots of babydust....
