Hi Flan 747,
Sorry you're feeling rubbish. I decided not to have the Mirena fitted in the end and am continuing with utrogestan. I too have really uncomfortable tummy at the moment - bloating, burping, gurgling and generally feeling too full despite loss of appetite. I'm also trying to figure out the cause. As you say, no doubt oestrogen related! GP prescribed me Omeprazole but that seemed to make it worse. Have you tried any treatments for it? I'm currently munching through my body weight in Rennies and have started taking slippery elm as suggested by someone on here. We'll see....
So hard to know what to do for the best isn't it.
