polyhydramnios (excess amniotic fluid)

Cat

Well today at my 35 week appointment I was told I have excess fluid and now have to have NST test done twice a week until they have two consecutive readings of my fluid being below 22! Right now my AFI is 27😰 Doctor says not to worry and I'm trying not to but cant help but worry and google doesnt help lol. I had my last ultrasound at 32 weeks so this excess fluid thing just happened within weeks!! In two weeks I have gained 6 pounds and no I dont have GD according to doctor everything other than fluid is perfectly fine!!! Anyone experienced anything like this or has more insight to ease the nerves!! Thanks
