Is this a sign?

Amy
I've just found out I'm 11 weeks pregnant, I went to my first midwife appointment last week. Whilst I was there my boyfriend saw 4 magpies in a row! 
1 for sorrow
2 for joy 
3 for a girl 
4 for a boy!
That was the first strange thing to happen. Then yesterday I got my first scan appointment guess what day it's on....my boyfriends birthday! Of all days! 
Are these just coincidences or what? 
This is our first baby and we were told we might not ever have children so we are rather shocked and excited!
