TMI WARNING! BV? Mucus plug?

Hi ladies. I hate that this has to be my first post but it's driving me crazy! I've had bacterial vaginosis my whole pregnancy. Never have I had discharge like this! I had about. Dime size snot looking thing one day, about a week later I see this! Then today I'm at work and I see another dime size snot looking thing. I suppose I should mention I'm 40 weeks pregnant. Someone please help me figure this out!
