Mucus plug?

Hope

30 weeks and having so much nasty discharge. Going through my kids clothes and my shorts were soaked and go to the bathroom and this is what I got. Was checked last week for it but was not dialated yet. Had the betamethazine shots 2 weeks ago for her lungs. I'm in the first stages of preeclampsia again. This is my second pregnancy being diagnosed with it. My son was born at 32 weeks from the preeclampsia but I never had any symptoms like this with him.
