For my last birth and for this one I have been an hour away from the hospital. I have always gone into labor in the evening so DH was home with me and it was my water breaking that made me go in. For you I would give your DH a heads up if you start feeling any contractions and have him head home if they start getting regular even if they aren't 5 minutes apart yet. It sounds like you might be a FTM so know that first labors are not normally very fast, but every woman is different. Is there any one who is close to you that you could use as a back up to get you to the hospital. I would let your doctor know about how far away you live and ask them if you should head to the hospital any sooner.
Re: Going into labor when hospital is an hour away?
I would talk to your husband and discuss a plan. Seeing how labor is generally slow, I am planning on driving myself or calling a cab if my husband is at work
For info- you could call an ambulance but they will take you to the closest hospital not the one you want to go to. Also, the reality is you have 9 mths to figure this out- so using an emergency resource because you didn't figure out a better plan isn't really appropriate. Please understand that there are most certainly situations where calling an ambulance when in labor is appropriate, but most of them aren't (in addition to my current job I used to be a 911 dispatcher so this is a bit of a pet peeve of mine.) in other words- start lining up alternate drivers, or consider an alternate delivery location is possible. (Again- my nearby hospital isn't contracted w my insurance but they by law have to not only see me when in labor, but also have to bill the insurance who then has to pay.)
