Period after Prostap with Mirena?

[HevsLM]

I’ve had the Mirena coil in for 3 years and still had periods every few months if not every month (question 1 – has anybody else’s periods just continued on it?), last year I had 6, monthly Prostap injections with my last one being on the 8th of November. I feel so hormonal, emotional, sore boobs, discharge, period/endo/adeno pains and have done for a few weeks but no period yet. Anybody else had experience of both the coil and prostap? Could I be waiting a while for a period? Thanks x
