KitKat~Gender cannot be found out prior to 16 weeks when the genitals become fully developed.The only way to find out before that time is by amniocentesis.You will need to wait til the 19-20 week morphology scan and even then,they can be wrong....ask LISE about it.She was told a girl then later at another scan,found out it was actually a boy!
2 Friends of mine,also were told one sex to give birth to the opposite!! I have had it checked 3 times to be sure from 19 weeks onwards and by 2 different obs,to confirm im having a girl and have seen it on the scan for myself up close..but i still worry i'll have a boy after it all.best of luck with your morph scan on finding out.
