"This does make me feel like I have people to run these things by!"
That's what we're here for. :)
Look, there is *no harm* in these tests, and with some blood tests, it might be better to have them run sooner than later (I found out, for instance, that I had slightly low thyroid - if it wasn't for an early blood test, I wouldn't have known and received the medication for it).
Just remember that you are in charge of your own health care, and you are responsible for the baby's welfare, too. Do what you think is right and best. You might feel embarrassed or uncomfortable to get looked at this early, but there really is no harm in it and you don't have to feel bad about it. *I* think it's too early, but what I think doesn't matter. Focus on how you feel about it, and yes, get a second opinion if you feel you need to. I wouldn't change anything right now until you get that second opinion - if I were in your position.
