First of all, God bless you and your little one.
I don't think your doctor meant anything negative, she's looking out for your best interest, you should let her know how you feel like a lot of the other mother's have said. Now, you also have to look at her point of view, she needs to have as much information as possible when delivering a baby. Just because you are consider high risk, just means they are keeping an extra eye on you. There is nothing wrong with that, you already know, that no matter what you are keeping your baby. I believe with you, that everything is fine with your baby. Your doctor does care about you, and a lot of those blood test tell more than one thing, they probably were just testing for one thing in particular but something else showed up. If she was just giving you an ultrasound and something showed up on it, that she wasn't looking for to begin with, you wouldn't be upset, you would want to know. I think the worse thing about being pregnant is wondering if everything is going right inside of you, then 9 months later, you finally get to see.
I really think she has your best interest at heart.
God bless you, your family and your little one inside!
