Thinking of switching to Mirena for PMS
Anyway, if it does turn out to work, I'm wondering about switching to Mirena a few months down the line. I'd rather keep the hormone dosage as low as possible, and taking pills is a hassle. I'm in the UK where contraception is free and the gynae I'm seeing is one of the best IUD inserters around, so swapping IUDs shouldn't be difficult. There's the minor issue of having to go through the settling down period all over again, possibly twice if I end up going back to a copper IUD. Is that less if you're moving from one IUD to another, is part of it your uterus reacting to the shock of having something in there? Also, if I move from the mini-pill to Mirena, will my body already be used to having progestogen and not make such a fuss over the Mirena? If I was already amenorrhoeic, for instance (which is pretty likely to happen, my periods are light and stopped instantly on Depo, I think about half of women on Cerazette end up without periods), would that just continue with a Mirena, or would spotting and such start up again?
The main thing, however, is how I'd react to the hormones. Both are forms of progestogen and both stop ovulation, but they're different progestogens, different dosage levels and different routes of entry, so to speak. So could anyone here who has been on Mirena or a mini-pill, especially if it's Cerazette, please tell me how you got on with it? If you tried both, how did they compare? Does the Mirena have fewer side-effects than the mini-pill? In particular, I'm very interested in hearing from anyone who has experienced PMS, whether it was before or during they were on hormones, and how the hormones affected it.
