I'm sure, because I go against the grain, I'm gonna get it from some judgmental women on this board, but I don't judge them for the choices they make. That being said, I had 4 unassisted pregnancies AND births (largest being 11 pounds about 8 months ago). NOT that I am advocating that for you, but here's an option: Do your own prenatal care and then when you go into labor, go to the county hospital.
(I have a friend who was on MediCal and her OB wanted to c-section her - because they get paid more for a c-section (45 minutes) vs. hanging around for a vaginal birth to last 12+ hours - but all tests are fine and baby was in a good position. She stopped going at 6 months and stayed at home during labor and then decided at the last hour not to go to the hospital. She birthed her 12 pound baby at home, no tearing, no nothing.
Birth was largely at home until the late 1920's in this country...so until them, all babies were born at home. The infant mortality rate for a planned home birth is the same as a hospital birth.
There's really not much to prenatal care, except that they have women hoodwinked into thinking it's worth a ton and it's not. Most of the tests are for high risk women and when insurance came on the scene, it became something the docs could make more money ordering.
Think about things logically, not hormonally. If the baby is growing, there is a heartbeat. You can get ultrasounds each week and that STILL does not ensure a heartbeat the next week. One week it can be there, the next it might not be. "Prenatal care" really does nothing for that. I get a massage each week during my pregnancy, as I feel like that is more CARE than being stuck with needles and taking tests that are largely incorrect.
So, here's what I do. I don't eat sugar, so I know I'm not going into gestational diabetes AND I also pee on urinalysis strips each week to keep my in-laws happy, so that checks the urine for white blood cells (infection), bilirubin, and 8 other things. A whole container of them run about $25. This is part of what the OBs and midwives check....you can do it yourself. Check the blood pressure every 2-3 week right now, and you can do that for FREE at CVS/Walgreens/RiteAid in the pharmacy.
I know an ultrasound tech that works in OBs offices and the OBs charge the patients $250, but the tech is only charging $75....so if you contact the tech, you can get an US for $75, but they are not necessary. (My friend was told her babies would not survive and they should start getting rid of her nursery things in preparation for their deaths based on ultrasounds. The limbs were short and there were problems. I told her they were wrong....based on intuition...and the fact that ultrasounds are often wrong. They convinced her of a c-section at 35 weeks (2 days ago) and guess what??? They are perfect, but small. No kidding???? You surgically removed him 5 weeks early!!! Ultrasounds are not perfect and neither are people, even docs! Now the babies are in ICU and not with mom because the are so small. The docs CREATED a problem that did not exist!) I don't consider an abortion for medical reasons valid for me, so I don't do any of the genetic testing or ultrasounds. That's me. I have a feeling, they are not as safe as touted....like fetal x-ray used to be. Time will tell, a the expense of our children and grandchildren.
Take a good prenatal, Nordic Naturals fish oil and PB8. Spend your money on good vitamins, otherwise don't take them. Most vitamins are synthetic. No fast food. Lots of veggies. Exercise.
So, urinalysis strips, blood pressure, weight, and exercise daily. Maybe try to get Hypnobabies CDs to listen to for a positive mental status. ;)
Have fun and enjoy this pregnancy!
PS My husband was nervous at first, when I decided to do an unassisted pregnancy (meaning doing my OWN prenatal care) but then he realized that the doctor simply monitors your "condition" because pregnancy is viewed as an illness that needs to be fixed. He realized that they do nothing for growth or health. They usually give out crappy prenatals and oils that are not bioavailable and then charge you to stress you out through a million tests. My births cost me $0.99 for the shoe laces to tie off the cord. LOL I saved over $22,000 for my births doing things MY way.
