I tried an IUD for about a year and it personally did not help but I’ve heard a lot of stories from women that it did wonders on their symptoms… unfortunately I think it affects everyone differently

I had I believe a Mirena IUD put in because I was sick of remembering pills. If not Mirena, it was another long lasting one with progesterone only.
After I started it I was bleeding mildly to moderately for a month and having awful cramps on and off, I think mood swings too. I had never cramped badly from periods or any form of birth control pill before, or even the combined pill which had caused a month of heavy bleeding. At one point the IUD pain got so severe I felt like I was dying for over an hour, so I pulled it out myself.
I cannot personally recommend them.
I switched back to the progesterone pill for years and am now looking into how to get off hrt fully and control endo without it.
