Yep sounds like baby is getting ready to come out! Do you feel pressure? When laying in bed, lay on your side, try stacking about 2 large pillows between your legs, that's the only way I was comfortable right before I had my daughter. It might be awhile before contractions start, but if your really uncomfortable, go get checked out in the morning. But more then likely you going to have to wait it out until your in labor. Might be soon though, good luck!
It sounds like pressure from the baby's head. Rest, drink lots of water!
