Mild cramping can still be part of the implantation process. Especially if you are very early in your pregnancy. There are a lot of great books full of useful, and sometimes scary, information. Just rest easy in the fact that most pregnancies ARE perfectly normal. You can't grow a new life without a little disruption of your own system.
You shouldn't worry about not being able to see a doctor or midwife so early on assuming you are up to date on your gynecological checks. They will do little besides another pregnancy test and establish a history. A pregnancy is either sustainable or not through the first few months--one of the hard facts of life I had to learn after multiple miscarriages.
The best thing you can do for yourself is rest when you can, exercise in moderation, drink plenty of water, and take a quality prenatal vitamin (I loved the the ones from NF Labs called Prenatal Forte).
Check your insurance. I had a midwife, loved my midwife, wouldn't have anything but a midwife...but all insurance doesn't cover midwifery care. It was worth it to me to pay out of pocket, but not everyone can do that.
Congratulations...I wish you all the best!
