How do I know if I'm losing my mucous plug? (TMI question)

Hey everyone. This week I have been having weird discharge and I'm worried it might be part of my mucous plug or something. It's sticky kind of like EWCM with a very very LIGHT greenish/yellowish color to it. It honestly looks like snot. I have no itching, burning or weird smells, so I don't think it's BV or yeast infection. It's not clumpy. TIA! Yes, I will call my doctor if I get super concerned.
