Removed IUD, what to expect, weight.

Just had my IUD (mirena) removed and it took a whole hour! It was awful, my doctor it turns out left no string at all, and it was placed as high as can be. I went to a different doctor since he was unavailable. He tried different speculums looking for it trying again and again to retrieve it all the while the nurse is saying the entrance womb has no nerves so I shouldn’t feel any pain, and just relax.

How will my hormones react now? I wonder if I’ll be fertile or not. It’s been in there for 5 years and before that I was on the pill for another 5.

Will this effect my weight? I am eating so little and in general eating very healthy but steadily gaining weight since early 20s. It annoys me so much to see literally everyone else is slim or at least stay the same weight eating all those high carb foods I eat so sparingly. And I keep getting bigger and bigger. I do nothing that’d typically cause weight gain and I am blowing up like Harry Potter’s aunt. I constantly need a new wardrobe I can never wear my clothes for more than a year or so. I go between being angry and resigning myself to a fate of blowing up until I just die.
