Mirena Issues

Hello, this is my first time on this site. I've been on a never-ending online search for the past weeks to find out what's wrong with me lately. It looks like I'm having side effects from the Mirena IUD that I had inserted 15 months ago after the birth of my daughter. I've gained 15 pounds in the last month (even though I've been dieting and exercising for about 4 months now). I've been constantly feeling pregnant; severe, painful acne, heartburn, cravings, nausea, dizziness, the list goes on. And now my body is changing to physically LOOK pregnant! My breasts have changed and my stomach is literally rounding out. I've taken countless pregnancy tests and they have all come back negative, thank goodness! However, I'm not thrilled with having these symptoms either way. I've also been dealing with extreme Depression and anxiety, which I've never dealt with before. Upon searching the internet for answers I came across several blogs by women who have experienced the same thing and the one thing I have in common with them is the Mirena. I also put it together that all of my symptoms started after my periods stopped. I'm beyond angry and desperate now.
I've made an appointment with my PCM for today to hopefully get a referral to see a gyno and have this thing removed. I'm afraid that they are just going to try to put me on antidepressants or otherwise dismiss my symptoms. I'm also incredibly worried that if they do try to fight me on my request to have it removed then I'm just going to breakdown right there and then they'll really think I'm nuts. I just don't know what to do and I'm really hoping that the doctors will just let me go forward with what I feel is best.
For others who have had this removed, how long did it take you to get back to being yourself again? I'm so tired of the crying, insomnia, constant fatigue, completely hopeless, and everything else that's going on with me and I just want it to all be gone ASAP!
Thanks for reading my little vent session. Tweet
