how important is the timing of the 19-weel scan?

I was told 19-21 weeks so you should be fine. I was 20w5d when I had mine.

Tenar, maybe make a phone call and ask what the time frame is for having the scan? The scan place I originally booked into would only do if I was at least 19 weeks and not after 21 weeks? i think?
OB wanted me to have it at 18 weeks, and they sarcastically told me that the Dr's don't know what their talking about, and that 18 weeks was too early, and they wouldn't book me in then.
