Should I test again or get my iud checked ?

Last weekend I had to go to urgent care for a UTI. I had been peeing all day like you do with UTIs, and could only come up with a thimble of pee. They kept asking me if I could be pregnant, even after they did a pregnancy test and knew the results. I have the IUD, and have had it move around a couple of times. Two weeks ago I could feel the tip of it, and now it’s straight up not there. I check my strings whenever I feel nervous about it, so I know how they feel and when they’re right. I did take a test after I got home from work today on a CB-Digital, and it said negative. Should I assume I’m good to go? Or should I test again in a few days with something else? I’ve been thinking about getting my iud checked but last time they said it was in its normal position even though I could feel probably 2-3 mm of the device. I’ve been on antibiotics for this UTI. My boobs have been hella sore lately, and I’ve had mild cramping. I have severe anxiety, so I get paranoid easily. I just want it to be the right time, ya know. I also smoke weed and REALLY would love to light up a bowl... lol!

Also would like to add that I have been ovulating again recently so that’s been stupid nerve-racking
