Dialated

So went to L&D today because of cramping and back pain and I am having contractions. They are about 6 mins apart. I am only one centimeter dialated and 50% effaced (the effacement was the last hour ) so they send me home... my back is killing me and I am having contractions still. I am 35 weeks today. Doctor appointment on Wednesday instead of the 21st.... I guess we will see how long this boy wants to stay in:p
