23 weeks pregnant, severely constipated, glycerin suppositories, high fiber diet, tons of water aren't working. what do i do now?

Miralax: Miralax is a water trapping agent that softens stool & works using this mechanism to avoid dry/constipated stools. The material also stays inside your digestive tract so it is quite safe during pregnancy. You can start with the dose suggestions on the container & increase or decrease amount and frequency as needed. It takes about 3-4 days to start working & can be used daily.
