Bloody discharge or show?

I had a cervix check yesterday morning. Today I've had bloody discharge all day, which I know is normal. It would be quite a lot to be just from my check. Every time I have gone to the bathroom, the there are a bunch of blobs and chunks of pink stuff in the toilet. Could this be my show? When I had my show with my daughter it was more like a big red mucus plug. I've been having nonstop back cramps and bh all day. I'm hurting so bad I just hope this is a sign the end is near.
