My doctor proposed too for the down syndrome test , and DNA test . But i forego because from my point of view , i do not want to get worried/stress unnecesarily since its my first pregnancy, which is not good too and might lead to other possible complications if we get too stressed on the result. And then i waited for my first few ultrasound , to see if there is anything wrong with my baby. Just my opinion and what i went thru up till today , 2 days until my due. All is well . Hope everything goes smoothly for you , and baby is healthy ❤
