I went for my 20 week Anatomy check up today. Tech was very nice. But when I asked her if everything looked good she just said Dr. Will let you know. But I have my next apt a month from now. My question is, if their something wrong do they let you know that same day ?? I’m a first time mom so it kinda worried me since she just said Dr. Will go threw it with you.
