Feeling guilty about being disappointed by baby's sex

I have always wanted all girls. When I had my son, I was thrilled and totally fine with having a boy. I just found out my second baby is another boy. I had such fertility issues and we tried for over a year, and I really want this second baby more than anything. I'll admit that I have really been hoping for a girl.

I'm feeling tremendous guilt about feeling a bit disappointed by the sex of the baby. I am so, so grateful to be pregnant and that the baby is (thus far) healthy. I'd love to get any support from you all.
