I will be 39 weeks tomorrow and last night I had to go into the hospital thinking it was time to have my beautiful baby girl, just to find out they where FALSE LABOR contractions!! I was so mad! The doctor even check my cervix and I was only about 1 1/2 centimeters dialated.... I can't believe it! I had a membrane sweep done on Tuesday January 12th and since then I've lost my mucus plug. Does anyone know any ways to help open the cervix and induce labor, that actually works?
