Muscu plug ? 35weeks

Kathleen

So last night after taking my shower, I have passed a big long (3-4cm) of what I think is my muscu plug... I show my fiancé and we laughed together because it was gross and on my hand . I didn’t take a picture but here is a picture of what he looks like.

What should I do or expect from that ??

I have some bad back pain lately too.

Thanks everyone
