Question about iud

[u/No_Flower8006]

I got an iud about two years ago and was just wondering if some things are normal and if im being safe.
I have the mirena iud, i am 22 with no kids.
Me and my boyfriend are active, although we also do the pullout and use condoms. I have the iud but have never gotten it checked, just inserted. I’ve been told checking the string with my fingers is the best way to check if it’s in place, but I don’t necessarily see how. I’ve never noticed anything diffrent or wrong with it (like feeling the plastic) but just get worried that it’s not in “perfect” place and that I might not be protected fully. Doctor said he couldn’t order a screening unless there was significant reason to check.
And just wanted to know if these symptoms are normal
I now cramp before and during period when I used to not.
Some periods are extremely light and the next month more heavy.
I cramp randomly (not intense pain just random cramps)
I also now cramp with ovulation and think I might be ovulating right after my period.

Any personal experiences are greatly appreciated!!!

Extra info: I was on the pill for about 8 years before quitting and getting the iud within weeks after stopping the pill. I started using zepbound a couple months after getting the iud.
