Questions about 3D ultrasound

I called and scheduled my appointment for Sept.3.  I will be 30 weeks.  But my question is, they said that I needed to make sure and drink at least 6 to 8 glasses of water or more a day for clarity?  and absolutely no soda or coffee.  I was wondering about how much water did you guys drink and if it was clear or not.  I just want to get the absolute best quality for my money.  Any advice or experiences would be so helpful.  Oh and they also told me to eat 30 mins before i came in.  Why??  Help.

I just went for a 3D u/s this past weekend and they told me I didn't have to have a full bladder and definitely didn't say anything to me about drinking water for clarity.  They did tell me to eat a meal approx 90 min before.  I thought the images that we got were really good and  I didn't drink much H2O before I went.  Maybe they use a different kind of machine?  Good luck, it was such a neat experience!

You shouldn't have to drink a lot of fluid if you're already at 30 weeks.  Things should be pretty clear.  As for eating first, I have no idea.  Enjoy your ultrasound!

It is more about how much have drank throughout your pregnancy. If you dont have sufficient amniotic fluid you will not have good pictures. As for the eating I was told when your baby is hungry they tend to move a bit more  so if you are eating approx every 2 hrs then baby will be getting hungry about then. Enjoy, I had mine done sunday and I have a DVD of Fionn aswell.

Thanks a bunch for your advice.  I dont know what to expect.  But I hope that it is clear and I cant wait to see her.  I still have this scare that they are going to say that it is a boy.  And we have all girl stuff and the room is pink and everything else is pink.  I am so excited to see her.  I cant wait!!
