Period with IUD (TMI)

I had a hormonal IUD put in at the end of May/First week in June. I have had a normal period every month since then. However, this month I have had clear discharge with blood only after I wipe for the last 3 days. It also doesn't happen all day, maybe twice during the day. I know that IUDs can cause weird things to happen with your period however I also know There's a slim chance of pregnancy.

I also know you can check for the IUD strings however I cannot feel mine. I never checked the strings on my first IUD which I had for 5 years so I don't know if that is normal or not.

Has anyone had something similar happen and not become pregnant over the following weeks? Or had there period stop soon after this happened?

Thanks!
