My wife is 3 week pregnant now yey :) But like every morning she don't wanna see me :( Is that normal for pregnant woman ? What should the best thing to do ?

Hormones! Some experience heightened emotions and some feel so down at times--and yes, that's normal. I suggest that you just let her be and just continue supporting her. There will be more mood swings to come--so be prepared. :) Pregnancy is very overwhelming and stressful but this journey will be a lot better with a supporting husband--like you.
