Woo hoo... after an entire week the nurse called me today to let me know the quad screen results.
For neural tube defects we have a 1/1500 chance (a positive test is anything from 1/100) so a strong negative. The results for downs and trisomy 18: 1/10,000!! A really, really strong negative (1/200) is a positive.
It was quite a relief.
A week from Wednesday we have our big scan. I'm looking forward to it much more now.
Who wants to guess the sex?
