Hun, my birthday is on the 13th, trust me, there is nothing bad about the 13th

Generally the morphology (20 week) scan takes about 1/2 an hour, depending on whether bubs is co-operating. They may tell you if they susect something is wrong, or they may tell you to see your Ob or MW.

It is rare for them to find anything wrong so just sit back, relax, and hope that bub does something cute like wave at you. We have a pic of DD2 waving at us, it was awesome!

If you want to knw the sex of your bub you need to ask at the beginning of the scan so they know to look.
