I've never had that form of birth control but my friend has had the same problem and end up having a second child I do not recommend that form of birth control but its up to you please contact your doctor cause it can cause medical issues
It could have moved. I would go to doc. Mine wouldn't stay where it was supposed to.
If I were you I'd get the nexplanon. Its a lil implant that goes in your arm. I've had it for six months. And i love it. It works great hardly any side effects.
I had that same problem. I had extreme abdominal pain and my ob/gyn removed the iud and told me it caused me to have a cyst and that was causing me agonizing pain.
