Last Wednesday, I went for my normal ultrasound check up, I was 17 weeks 6 days. My Dr told me that I would be back Wednesday (one week) for my "Big ultrasound"..

So, this is my first pregnancy and they didn't tell .e anything about it or what it was or anything and I didn't think to ask..

What all will the do? I'm just curious!
