Warning TMI. Weird discharge?

Went to ER about it,.I had no clue that it was that bad when I went, apparently my cervix are extremely inflamed. I had green stuff coming out (which I had never noticed) they tested me for yeast, bacterial infections and STD. Everything came back normal but I have to wait on the STD test. To be honest I'm confused, I have been married for 2 years and only have been with him since we met and i know he is faithful too. We had a baby last year so I would have assumed they tested for that but never did a Pap after I had her. I am terrified its bad news and I am pregnant right now and have a UTI. Anyone else have this problem?
