Doctor worried me today...

she called and said she found something abnormal in my sonogram. she says there's a lot more fluid in my amniotic sac then there should be and that she's gonna call a specialist and schedule an appointment. I took my glucose test and was at 138 when you're supposed to be at 130 but my doctor told me she doesn't think it's diabetes. I'm freaking out, super nervous. anyone else have to go through this? please inform me :( worried first time momma.
