Girls, if the labor doesn't start by 40 weeks Should I go to the maternity ward myself? Or wait? I'm 39 weeks and 3 days and I'm really worried My first births were pre-arranged etc How should I be? How can I call or prepare for childbirth? I'm tired already Plus my son is older sick with him, I can't help ? everything is so overwhelming
