Mucos Plug or maybe something else?

FTM and I am 35wks and 3days. went to the bathroom and found this on the toilet paper. it's pretty thick and very gelatinous. not super sticky but I'm just wondering if this could already be a piece of my mucos plug coming out or if maybe it's just discharge that's changed now that I'm farther along. I read you can lose the plug starting at 37wks so that's why I'm kind of puzzled. any input helps. thank you.
