Measuring 3 weeks ahead 😩

Randie
I'm 25 weeks as of Tuesday and went for my OB appointment wednesday, doctor was doing the measurement and heart beat and come to find out I'm measuring 3 weeks ahead of schedule. Had to get an ultrasound right away. Baby is fine but I have to much fluid. So I had to get my glucose test done yesterday(Thursday and I'm still waiting on my results) my doctor had told me a few different things, it could be gestational diabetes, I have a blockage; where he is drinking and peeing but the placenta isn't releasing the fluid to me and if that's the case I will be delivering even sooner then expected (scheduled c-section May10th). I don't even remember what else the doctor said because all I could focus on was my son coming early and he isn't ready. I'm officially high risk and I'm freaking out. I don't know what to think and looking on "Dr.Google" isn't helping. 
Has anyone else gone through this, if so can you help me out?Â
