Mucus Plug? (Graphic-ish)

Ke

My husband and I had sex last night around 9 p.m. he finished inside of me and after I went to go clean myself up. This morning I had work (my doctor instructed me to drink a gallon of water a day). I had been going on bathroom breaks since 6 a.m. and around 11 a.m. I noticed something that distinctly looked like what has been described to me as a Mucus Plug. Now I'm only 32 weeks pregnant and I haven't had any signs of labor, but is it possible to be my Muscu Plug that I noticed or reminents from last night?
