IUD only 1 string and weird pains

[Anonymous995]

I check my strings every couple of months and usually feel 2. I’ve had mirena coil for about 15 months now. Recently it’s been weird heavy discharge, pain, bleeding after sex and weird internal pains, I even took a pregnancy test. Is it worth getting this checked at the GP now that I can only feel one string, given the other symptoms too? Or can it be normal to feel one and only worth checking if you don’t feel any?

The strings are one tied thread, so feeling one isn’t an issue. The other one is probably just coiled up or something.
You should see a Dr to get checked out because of the other issues though.

Thank you!!
