Dr. or just a good guesser?

Week 35 arrives on Thanksgiving. That is the point that the Dr's said was a pivotal point in the pregnancy. If we got to 35 weeks the odds were good that everything would be fine if they were born. As you may remember Andrea and I thought that she had a condition called cholestasis which jacks up the liver and can negatively effect the babies. The Dr. said that she did not think that she had it but we pushed her to check for it. She reluctantly did and the results came back today that she does have "cholestasis of pregnancy" This occurs in 1/1000 pregnancies so based on our recent luck we were sure that she had it. When we called them and told them we thought she had shingles they said that it was a skin yeast infection and my wife had to suffer longer than was necessary. We have been told by one Dr. that if she does not have the babys by December 10th that they would go and get them between the 10th and the 17th. Today she said that they would wait until between the 17th and the 24th. Then she wrote the prescription wrong to treat the cholestasis and I had to wait an hour for the pharmacist to clarify the order. I also asked the Dr. if we were able to use over the counter version of Prilosec. I asked because the prescription version cost me $55 last month and I bought the over the counter one tonight for $16. If it was fine tonight why were we not told this last month? Some one owes me $39. No real money saved though because the new medicine that she starts tonight has a copay of $60. So here is the question to the Dr's of the world. Do you make this crap up as you go? Do you really know what the hell you are doing. Oh, and by the way, Blue Cross Blue Shield, you suck!
