Unassisted prenatal care?

Karissa • Expecting #3 in September
Hoping you ladies can offer some advice, (sorry so long) a lot of moms see even stretching out the 4 week prenatal appointments as neglect to their baby but I just don't agree with all the stress of so many unnecessary appointments. Ok so I have an OB and went to my first dating ultrasound and got the basic check my stats bloodwork and generally have nothing against medical care when pregnant. My situation is i'll be traveling a lot while pregnant and feel that this being my third I know my body enough to take care of me and this baby through much of my pregnancy. I've been doing some research and there's whole support groups and books for moms that do it totally on their own conception through birth, I'm not that brave I do plan on going to a hospital for delivery and possibly getting checked out again by ob toward end of 3rd trimester. So I guess I'm asking if anyone here has done this or at least limited their checkups or how often do you go? Thanks in advance!
