I have had my IUD for a little over a year now. I have had my monthly flow, sometimes closer together, sometimes a little late. This month, I’ve only spotted which was brown in color. Two days ago, I had a LOT of discharge that was kind of yellowish and was VERY sticky. Over the past few days, the entire right side of my abdomen has been getting increasingly sore and hurts all day… I’ve been overly tired as well

I got the IUD to prevent pregnancy but I’m scared it didn’t do it’s job… Has anybody else experienced this? Can anybody give me some information or feedback please before I buy a test
