Any contractions? If you have contractions time them. If they get down to around ten to five minutes apart its time to have the baby. Call doctor in the morning to let them know you are having pressure already. GL
Uncomfortable but normal. Try resting as often as you can. Lie on your left side. Alternately, take walks to get circulation going, and the baby may shift positions too and relieve some of the pressure. Don't stand for long periods of time. Don't strain when you go to the bathroom.
