Hi, I'm 43 and have had mirena coils fitted since my DD was born 18 years ago. been happy with it as my previously heavy periods dropped to almost zero...would have mild back and tummyache, followed by light bleeding for a couple of days every 3 months. However, since i had a new one fitted a year ago, the bleeding has been replaced with thrush and if i do have a bleed (last one was June,) it has been literally half an hour of light spotting) but since then i have been getting regular (monthly) PMT like i'm a teenager with an anger management issue and bi-polar. eg. i cried for 3 hours because my DH wouldn't let me nick a chip off his plate.. then screamed like a banshee into the mirror because i had managed to miss a bit when i home-dyed my hair. added to that the aches, pains, insomnia...i have also had a few hot flushes, but have had sinus infection recently so it may be that...any advice would be helpful..i don't want to waste GP's time if it's avoidable.
