String problems

Tara

So I've only had my IUD for like 4 weeks now, I've been checking my strings like every 3 days or so like my Dr said to do. Well after sex the other day I noticed my strings feel different, like they are wadded up and over to the side, totally not where they were before. Should I be concerned 🤷 I haven't been having any issues, just worried my IUD moved or something
