Is this normal?

I’m just over 13 weeks but for the past almost 2 weeks I’ve had a few (more than a few) times where I’ll get heavy vaginal pressure, cramps, then I pass a large amount of discharge. It’s super thick like a sneeze discharge. Then I’m fine til the next time. Any idea what’s causing this? I told my doctor about it and he didn’t listen to me it seemed like so I go to a different one this coming week and I’ll address it there too.
