My first IUD i had no issues with. Although the last six months I do seem to get my period and I also started having infections after having sex. Nothing major to worry about. I removed it put in another IUD and it just seems like this time I have a lot of pelvic pain I’m bleeding heavily after intercourse and I seem to have an infection anytime I have sex. I did not use the same doctor for the second time that I use the first time. I wonder if it’s just how the inserting or how it’s placed.
