First check up Q:

So I have my first check up scheduled for May 26th, by then I'll be about 9 weeks along is my estimate. Will the doctors do a sonogram? Or could I request one do you think? Because I want to see if I'm having twins. I kept seeing other women's posts about getting sonograms(ultrasound) done at 4-5 weeks!! I didn't think that was even possible till like 20 weeks but if it is then I want to do it!
