Mucus plug or extra discharge?

I am 34 weeks today, perhaps a little more active then usual, just wondering your opinion...I mean I know discharge increases in pregnancy but this is more than usual for me. I do feel like baby is low down first child was born at 37 w second child was 36 w. Never seen my mucus plug with other two kids I do have gestational diabetics (read it can cause preterm labor)....not to many bh contractions but did have cramps other day perhaps I’m just googling to much
