Is this normal?

I am 37+6 and I am losing huge chunks of mucus plug kinda tmi but like it’s to the point they don’t come out on their own I have to get them out kinda chunks but no bloody show or consistent contractions yet I am having contractions just not regularly at this point! How much longer do y’all think I have before I have my baby boy

Oh and last doctor appointment she said I was 4cm and 75% effaced also!!
