Hey Nas,
Whilst time differences aren't the same, I had mirena coil in October last year, bled\spotted until January. Then nothing, the in March a bleed for 10 days with cramps etc. This month, no bleed but terrible moods and dips. Mine seems to be cyclical? But I am peri, so still getting monthly hormonal surges at same times of month.
Not sure but it helps at all as I think you are post meno? Maybe the increase in dose has stirred things up again?
Sure someone will be along with some actual advice.
Sorry for you Nas as I know things seemed to be improving for you. Too many false hope scenarios that we have worked this Crap out.
Hugs as always
