Hi all

I'm almost 17 weeks (1st pregnancy, 23 years old), and to date I havn't had any screening for downs or spina bifida. When i went for my 13 week scan the sonographer lady did ask if i was having the nucal translucency, i wasn't as my doctor hadn't specified it on my referral. The sonographer said that it was fine and its up to my doctor.

I have got my referral for my 18-22 weeks scan, and my doctor said this will be a "detailed" scan for any abnormalities, this is specified on my u/s referral. Does this pick up downd syndrome?

Should i be requesting any other screening tests?? Like the blood test that can be done at this time in the pregnancy. I have read so much about the various tests that can be done, and the more i read the more i get confused. Because my doctor hasn't mentioned anything other than this detailed scan, that will test for abnormalities, I didn't think i had to go for additonal tests.....i am now scared that its too late?

Any suggestions as to what is going on, or what i should be doing??
