Mixed Emotions

5 years ago I was diagnosed with PCOS after losing my first and was told having kids would be greatly difficult for me. Then I had a beautiful baby girl July 2016 and just found out yesterday I am pregnant again....I had kind of come to terms with only wanting one baby especially with the complications during the first and second pregnancy but at the same time part of me wants more. I don't want an abortion or give the baby up for adoption but part of me is still dealing with depression from the last pregnancy and I just don't feel as happy as I should feel. We've been extremely careful this last year and the one time the condom breaks I get pregnant.

I want to be happy about this pregnancy and I am, I'm thankful just not as happy as I feel I should be. I honestly was in complete shock when the pregnancy test came back positive. Could it be because my hubby and I are going through a little rough patch? Been married 7 years. Does anyone have any advice whether they have some what gone through the same thing or not?
