Super short super heavy periods, any tips please ?

[Gembob1]

Hi ladies. I'm new on here, from UK but now living in Australia, diagnosed 6 years ago, due to have 3rd lap in a couple of weeks. Recently also diagnosed with adenomyosis and under active thyroid, so tired all the time and getting new pains including in my legs and up to my ribs. Up until recently I've had pretty regular periods lasting 4 to 5 days, painful and heavy with clots. The last few months however they are irregular (10 to 40 days), they only last 2 to 3 days but are incredibly heavy with flooding and huge clots and so painful I cannot work. Has anybody experienced anything similar? Have any tips or medications I could try? Thanks!
