No morning sickness!?!

Ok so...we found out we are pregnant about 2-3 weeks ago.... When I check my due date it comes out to be January 11th 2016...witch would make me 7 weeks 3 days today....

I only have sore breast, bloating and I'm always hungry...I also have heart burn....the one thing that worries me is no morning sickness... Only because with my 4 other children I always had it as soon as I knew I was pregnant.....

My ultrasound is on Friday and I'm kind of freaking out :(

Anyone else having this problem? And has had their ultrasound??? And everything be ok?????
