NOT BV

I've had greenish cervical mucous since the beginning of my pregnancy. I've gotten it checked out 3 different times. I do have a yeast infection that won't completely go away but otherwise I've been swabbed for everything else including BV and it's all been negative. Starting at around 12 weeks the discharge has become abundant! Not all the time but maybe once a day it kind of builds up and it is green and snotty. Has anyone else dealt with this in their pregnancies?!
