Lost mucus plug?

Okay I'm almost 37 weeks.. When I got out of bed I felt the urge to pee so went to the bathroom when I did it felt like something plopped out not like pee.. Kind of like a ball drop when I looked in the toilet I couldn't see anything but when I wiped it was a creamy white kind of like boogers or cum.. I havent had sex in 2 days so I know it's not cum from my fiance.. Could it have been my mucus plug? Should I go into L&D?
