Hi There, At 14 Weeks My Water Broke I Gushed

Hi there, at 14 weeks my water broke i gushed a lot of fluid long story short specialist sees barley any fluid in the sac two weeks later still no fluid but baby is growing and still has a strong heartbeat, i’ve read a lot online about increasing fluid i’ve been drinking between 150-200 ounces of water a day i’m on bed rest but i’ve read that stevia helps increase fluids and taking 20 minutes baths helps as well. is this true ?
