I visited our naturopath for advice on nutrition last week. Last pregnancy, I feel like my nutrition could have been better, and she gave me a few pointers. I'll go back in and get a hemoglobin check around 7 or 8 months (I had too much blood loss last time, so I'm being cautious). That's the only outside care I'm planning on. I have a post here
about what she went over, if anyone wanted to see.
On my own I check my fundal height, and use a fetoscope to listen to baby's heartrate after about 20 weeks. I'm going to buy Emergency Childbirth and read that with DH. I track my weight as well, and I'll buy urine sticks if I feel the need to check that.
I wouldn't hesitate to go in for an ultrasound or even a C-section if I thought it was needed, but I really don't think it will be.
ETA: I'll get a pregnancy confirmation at our local 'crisis pregnancy center' just to have on file. I do like to have that. I also have a friend (and MDC mama) who's a midwife, so my bases are covered there if the state gave me any issues. I didn't have any trouble with my DD who was UP/UC, so I don't expect it will be a problem with this one either.
