This may sound like a really dumb question, but I just woke up and under me was wet. I was holding a puppy who was asleep the whole time so I'm not sure if maybe the puppy had an accident in her sleep or if my water broke? I'm a day away from my due date so I'm concerned due to my doctor saying to come in ASAP if water broke. Is there a way to tell if water broke? Have been experiencing cramping and feeling more pressure lower down than I did earlier today as well...
