I got a boy with pH of 4.5 and we've seen so many pH opposites in both pink and blue sways, it's hard for me to believe in pH any more. I have an essay on the science of pH and why it can't possibly work in the way the other sites claim that it does here:

Those foods are good boy foods but I hope you're also getting protein with them and lots of healthy fat. "alkalinizing" foods don't really sway, what matters is the nutrients in your foods helping to make you more fertile.

How much folic acid are you taking?? You should be taking 2000 mcg per day and I would also like to see you taking fish oil, a prenatal or other good-quality multivitamin, Vitamin D (up to 1000 IU a day). Those are the most important supps and then there are others that may help but are less important.
I believe Preseed helps a lot and we've gotten very good results with it.
