Could do with some advise please!!

Hey ladies, this pregnancy stuff is all new to me. I have learnt so much from reading your stories and could do with some advise from women who have been there. My wife is 2 months pregnant and this is our 1st. My wife is so scared of having a miscarriage, she seems to get up set often. I'm worried that her getting stressed and worried will cause something bad to happen. She had some brown discharge and a little pain so we sat in the hospital for 4 hours. All was well. Then she complained that her boobs weren't hurting and that she doesn't feel pregnant. Through reading the stories on here, I know that discharge and symptoms coming and going can be totally normal. I know it may sound like I'm ranting or complaining, but I'm not, I know she is just nervous and scared and I cannot fully comprehend what she is going through. But when she works herself up and gets worried and panicked, it eventually works me up to and then I become no help to her. What advise would you give to help calm her or reasure her that all is fine? Or do I man up and just allow her to think what ever she is thinking and endure it????
