20 wks scan they look each organ of baby.. just to see any abnormalities... she will also measure amniotic fluid...they look at heart, measure head n brain, limbs, arms and legs, everything almost... they also tell you gender if they are able to see....
about blood test if any of you missed before then yes they probably will ask you to give them...
take cares and best of luck
Alright thanks I figured that's what they do.. no blood tests right? Lol I hate getting blood drawn!
they look at all the babys organs and check the size and sex
