I was informed last week that you can find out the gender of your baby from the blood test results of you Down syndrome test that's stuck into your pregnancy book, it reads that I will be having a boy, but find out on my 20wk scan next week for decimate! My friends indicated boy and she is having a boy! Anyone else impatient to find out what there having???
