Help I’m scared

Update: tested negative for amniotic fluid. Waiting for an ultrasound now. They said she most likely was pressing really hard on my bladder which made me gush out pee 😳🤦🏼‍♀️ so happy she’s ok and staying inside though!!!

I’m only 21 weeks and when I woke up I went to get a cup of water and a lot of clear liquid poured out of me. I called my ob and she said go straight to labor and delivery 😩 what else could it be besides my amniotic fluids? Praying for a miracle.
