Anatomy scan

Ba
I'm having my scan in a 2hours.. I'm nervous... Very nervous actually. The baby's been perfect up until now I hope he is great still and everything normal. I'm more concerned cause I found out a cousin of mine was supposed to give birth more or less a month before me but her placenta was not nurturing the baby in fact she was killing it. So the little one was born with 25 weeks. She found out on the anatomy scan so now my brain is over working -_-
