Iud help!

Lauren • Wife, mommy to a little boy and a baby girl

So my fiancé and I had sex last night and there was some bleeding after and I googled it and it said it could mean Mirena expulsion

So tonight I decided to check my strings and all I could feel was something plastic

Does that mean my Mirena is expelling, has anyone else experienced this?

Also should I take a pregnancy test if this is happening?
