Question @31w

I have been having this sensation in my vagina and it feels like the baby is trying to break my water (only know this feeling cause with previous pregnancies my dr has broke my water), I get a sharp cutting feeling in my vagina/pelvic region, contraction like feelings, less fetal movement than a few weeks ago, diarrhea practically every other day, feel nauseous and have heartburn and acid in my throat all the time, also having to go pee a billion times in a row but not much but comes out at all, leaking clear non-odor discharge .. guess my question is has anyone else dealt with this so soon? Im 31 weeks and 5th pregnancy.
