Hi A.,
I just have a couple of things to add to the great feedback you've already received. Contractions typically start around 6 or 7 months of pregnancy but women don't really feel them, or they just feel like a slight tightening of the stomach with no pain. The closer you get to birthing your child, the more frequent and intense they get. So in reality, your body is already starting the birthing process but it's hard to know how much longer you have to go! It can be crazymaking for sure but try to trust that your body knows what to do and don't let fear rule your mind. Besides, unless you want another epidural right away, the longer you labor at home, the more comfortable you'll be. Like the other moms said, call your doctor or go to the hospital if you have concerns. Also, don't worry too much about the cord being wrapped around the baby's neck - it's VERY common but is often used as a scare tactic. As long as they know that it's wrapped and they're checking periodically (in active labor) to see that the baby is not distressed, it's easy to slip it off once the head is out during delivery. Try to relax and enjoy the process - I probably sound crazy but you're bringing a new life into the world and women have been doing it since human life began. Amazing!!! And you may be one of the lucky ones who doesn't have a lot of discomfort from contractions :)
Good luck and have a safe, healthy and joyful birth!
