33 weeks discharge

I am almost 34 weeks on Monday and for the past 2 days I’ve been having extreme pelvic pressure and heaviness with back pain. Today I woke up and I have been having aching in my cervix it feels like. Well I was sitting on the potty and I could feel the cramping and when I got up I had a ton of discharge in the toilet and when I wiped I had snot like mucus discharge. Is this normal for 33 weeks?
