mucus plug??

Erin
Hey guys I'm 35 +2 and a FTM. Yesterday I had a lot of cramping and lighting crotch (sorry tmi) to the point of bending me over. Nothing super consistent or concerning though since my doctor says that's fairly normal, and I understand that at this stage of pregnancy there is a lot of pressure in my pelvis and that's just sort of part of the deal. BUT this morning I went to the bathroom and a large string of clear rubbery type mucus came out, not bloody or brown. Could this be part of my mucus plug..? Thanks!!!
