37 wks pregnant, pressure in pelvic and mucus discharge?

I am 37 weeks pregnant was dilated to a 2 last week and my cervix was extremely soft. My c-section is scheduled for July 6th. I am having alot of braxton hicks and lots of pressure in my pelvic area. Also, when I wipe sometimes I have mucus discharge. I am finding it very hard to breath anymore and it scares me. The doctor says its a 50 percent chance I want make it to my scheduled date.
