I am looking for advice or maybe just someone to help validate that I am not crazy.

I had a baby in May, lost 30 lbs by August. Still about 20 lbs from my prepregnancy weight. I had a Mirena placed first week of September.

I have consistently gained 10-12 lbs every month since then without any changes to my diet or activity level, other than trying to cut down on calories and carbs once the weight gain started. The weight gain is really affecting me mentally, I feel completely depressed and hopeless. I am tired, sluggish and everything is so hard to do. Every week I can feel my clothes getting tighter despite everything I am doing to stop the weight gain. My face has ballooned, its almost unrecognizable in pictures at this point. I do not want to be that patient that goes back to the doctor and blames their weight gain on their birth control but maybe it really is from the Mirena? I just don't know. I am at a loss here. Has anyone else experienced this or have any advice?
