End of BV or Mucus Plug?

Mai

I’m on day 9 of a 10 day course of FLAGYL for Bacterial Vaginosis & I haven’t had bad discharge this whole time & today I wiped 3x and got 3x big clumps of this.... is it the end of my BV... or a mucus plug? I’m 33 weeks pregnant today.... I have a Dr. Apt in the morning but would love some feedback xx thank you sorry for the TMI pic
