Nuchal Scan

I had a Nuchal scan on Thursday, was amazing, so detailed, go to enjoy seeing my baby from every angle and hearing the heart beat. loved every moment ...my husband was also there and he just looked amazed! The Baby measured 13 weeks. I also asked  the technician whether she could guess the sex of the baby and she said " its only a guess, it could be a little boy" she said is not definite as its still too early to know the sex for sure. I am or was very sure I was having a girl, now I am confused and not sure which one...  my hubby wants a little boy but truly i don't care about the sex although its nice to know as long as it is a healthy baby ... The result from the Nuchal scan turned to be all normal and low risk. Thanks god for that.
