weird cervix after giving birth

Ja
I have two kids, my last one I have at the end august. I got my period nov 5 which I wasn't expecting bc I'm breastfeeding exclusively.. anywho I always check my cervix when it gets close to my period day so I check it last night and it feels like something rough is hanging out of it! It totally freaked me out and make me instantly nauseous.. I don't want to feel it again so my husband said he will check it later tonight after work!.. I'm totally freaking out and I don't know what it could be or what I should do! Anyone experience this or something similar? Someone just tell me to relax😳
