wife pushing me away

My wife is now 10 weeks prengant.We have planned on having kids but not for a few more years. She was happy about the news and so was I. But one week after finding out the good news she has since kicked me out stating she needs space. It has been 3 weeks since and we barely talk and i have not seen her. She says the sight of me , the smell of me makes her sick. She has become totally distant from me. I do not know whats going on. wendsday i went and talked to her mother, father, and sister about the whole thing. They dont understand what she is doing either. im trying to hold on and be here for her but nothing i do is the right thing. Last night she found out i talked to her mom and she is very mad at me for it. Im taking it her mother had a talk to her. I am starting to wonder about the whole thing. Could this be a hormone imbalance? Or is this normal? A lot of our friends have kids and they did not do anything like this. Any advice?
