Oh sorry I started to answer this the other day and got interrupted.
Tell me more about why you believe that you are too acidic. A lot of the stuff written about pH on the Internet is inaccurate or downright false.

Do NOT try to do at home IUI. It is very very dangerous, and I know they do sell kits to do this online but it can kill you or permanently make you infertile. IUI done by doctors, I do believe can help sway blue, but we are getting very good results for boys without it and I do not think it is worth the expense. Do not use Clomid if you are going to do IUI at a doctor's office, it sways pink.
There are many things you can do to sway gender that are very safe and effective. My recommendation would be for you to do HE Diet, multivitamin, 2000 mcg folic acid, fish oil, up to 1000 IU Vit D, and lift weights. For your husband, he can take a men's over 50 vitamin, fish oil, and extra Vit. D as well. I recommend having unprotected sex every 2-4 days, use guanefesin to make more EWCM (this will also raise pH) and also Preseed.
