Paragard IUD and weight gain....mainly around the abdomen

I’ve had my iud for almost 5 years now and I’ve recently started thinking about getting it removed, i haven’t had any major reasons to do so but the more i research the more i realize my iud has caused a few side effects. I am now the heaviest I’ve ever been even during all three of my pregnancies and the most noticeable and annoying part is in my midsection. When i first got the paragard i noticed my abdomen would be sore on my right side from time to time for no reason but i haven’t experienced that i a few years. But if my husband rests his hand on my stomach while in bed it is very uncomfortable and i remove his hand. My periods pre iud would last for 5 days now they are heavier and last 7-8 days. I️ would just like to know if anyone else has experienced anything similar with this form of birth control...
