Excess fluid


Has anyone been told they have Polyhydramnios? I found out yesterday at my 32 week growth scan that I have this. Also my placenta is now anterior where it’s been posterior up until now. I’m freaking out after googling it! I had GTT at 26 weeks and I passed, they’re making me do it again this weekend along with other tests to try and figure out where this extra water has come from. Has anyone else had a similar experience? Was everything okay?
