Mucus Plug

On Wednesday I will be 34 weeks and I'm almost positive I just lost my mucus plug. I lost some of it at 5 1/2 months, went to L&D and everything was fine, they said it happens sometimes. This time, it was A LOT more but there wasn't any blood or anything which the first one a few months ago didn't have any blood either. Only difference this time, I was having horrible cramps like I had to go to the bathroom, so I went but only went pee and when I wiped there was nothing but a ton of discharge and mucus(I could tell the difference between the discharge) and I'm still having cramping. My next doctors appointment is on Wednesday and of course my doctors isn't open today. Do you think it'll be ok if I just wait till then? It's really hard for me to just go to L&D because my boyfriend has the car and is at work and he will get in trouble if he has to leave.
