You didn't mention how old you are, but many women of all ages started getting hot flashes after getting the Mirena. I was in my forties when I had the Mirena inserted and never had a hot flash until it was inserted. Unfortunately, 6 years later and 1 year post removal, I'm still having them. The artificial progestin shuts off your own progesterone and really messes up your delicate balance of hormones.
