I did hear quite a bit about this from other mums! The thing is, 10 weeks is technically doable, but you're walking a bit of a tightrope with fetal fraction, basically how much baby DNA is in your blood sample. Some mums I know got clear results at that stage, but a few had inconclusive results come back because the fetal fraction was too low (I think one mum's was over 7%), and then they had to retest a couple of weeks later.
