Vi: Oscar mainly tests for down syndrome and it is not 100% accurate. This is also calculated against your age. so if you are 35 or older, the risk is higher, But that does not mean the bb will have down syndrome. This is what I know. Also heard of few stories that although results not good, bbs borned are of perfect health!
Shirley: I thought second semester is after 13 weeks..not too sure too. I have never taken durians during my pregnancy, even for #1. And just the last visit, sugar was detected in my urine, so I must watch my sugar intake. My next visit, my gynae will advise me on this sugar level..haiz.
