False Labor


So I am now 40+4. Went to the hospital today because I was cramping. I really thought that I was in early labor or they would at least induce me. They checked my cervix and I am only 1.5 centimeters dilated. I was so upset when they sent me home. The doctor did a membrane sweep so hopefully that helps. They told me to either come back at 41 weeks or if my water breaks before then. At this point I just have to be patient even though my patience is at 0. Did the membrane sweep work for any of you guys?
