help!--loss of bladder control?!?!

I am 4 weeks pregnant and just woke up after only 3 hours sleep and thought something felt off (and nauseous as usual) and I started to roll over and then something started coming out of me- like how it feels when your water breaks or something.  I freaked out bc I thought it was blood and I ran to the bathroom with this liquid falling out of me in the dark room.  Turned out it was pee but I had ZERO control over it and it was just falling out of me- not like I held it too long but like my bladder took the night off.
