I have the mirena in so no periods which is fab, but trying to work out where i am peri menopausally. I'm 45, and for the last 6mths have had sore boobs, gained weight despite improving my diet, aching joints first thing in the morning, waking at 5am, and most of all, feel very crotchety. I'll probably ask my gp if I can check my thyroid as that went off kilter a few years back, but has been fine since. I know everyone is different, but did anyone feel similarly with the mirena, and improve with Oestrogen?
