Elevated fluids, big baby & more

So I'm at the doctor for my 36 week checkup. I had an ultrasound to check for elevated fluids since I've been having so much swelling. Turns out my amniotic fluid level is way higher than it should be and baby is measuring 7 lb 14 oz. I have to retake the glucose test bc they think I have gestational diabetes, which is causing the baby to grow so fast. I'm so nervous and scared at the same time. Anyone else experience something similar?
