IUD after effect

Hey ladies! So I got my IUD inserted on the 22nd of January and spotted for about 3 days after that. On the 31st of January I got my period (at least I think that's what it is) I'm going on 16th day of bleeding and I'm so annoyed ! 😡 the bleeding goes from light to heavy, when it's light I think THANK GOD it over and then BOOM it gets heavy, & don't even get me started on the cramps ! I feel like shit. I feel bloated and I feel like IUD is making me just want to eat. 😭🙄 I honestly feel like I've gained weight since I got it . What was your experience like ?
