Am I leaking fluid? Help, FTM

Kirsten • Pisces. Dreamer. Free Spirit.
I woke up about an hour ago to find my panties were extremely wet, and it wasn't urine. I called my OB and I'm currently waiting for them to call me back. I haven't felt my little one move since I've been awake so I drank a cold glass of orange juice and went to lay on my left side. I'm a FTM and I'm not sure if it's my water leaking, or what else it could possibly be?
