Pregnant... But not happy....

I was one of those people who just felt like a baby was never in my future. After trying for such a long time and being told I won't be able to conceive naturally I have PCOS and a hormonal imbalance.. So every single month around my cycle I would take a pregnancy test and get what I've always gotten. Bfn. That's what I had expected for today same old routine three days prior to my period would take the test get my negitive and go to my wine for comfort.... 

Today worked out a little bit different, I took a wondfo test and saw a faint line after 10 minutes (even though I yelled at the test and asked it if it will ever be two lines) ....... Didn't trust it so I got a digital and the first response........ Both were positive. I just don't feel happy for some reason ..... I don't feel what I thought I would feel ... I just feel numb.... I've been trying for two years and I wanted a baby more than anything and I still do but I just can't figure out why I am not happy or crying or anything... Just numb
