contractions for the last 40 or so mins have been 3-4 mins apart. theyre really uncomfortable and cause me to make noises but theyre not so painful that im in tears or anything. and it keeps feeling like im peeing my pants but nothing is coming. if it keeps up for the full hour plus, should i call and try to go in ?
