your doctor gave you hcg to make some extra $$$ off of you
just like how doctors in the US do C-sections at a much higher rate than anywhere in the world.. they want you in and out quicker, gotta make more $$$. the days of a women being in labor 2 days are gone in the US. they want that baby out ASAP.
i will give you some advice i have learned.. never depend on a doctor for your own health. i see this too many times.. people just take what the doctor gives them without doing their own homework. if your doctor is that insecure where he gets offended by you turning down more drugs, then you should find a new doctor
