I have Aetna and I don't live too far from St.lukes east hospital in lee summit, I was planning on going there for an ultrasound but wasn't sure how much is covered. I'm 11 weeks long, should I wait tilll 20 until they consider it "necissary" like some people say or should I grow some guts and drive there to ask? I'm 16 and learning all of this alone.. any advice would be greatly appreciated!! Thanks.
