If you alkaline your body, then you are also doing the same to your vagina. Urine is usually always acidic, im not sure about saliva, but i think that always stays around the same ph aswell. Whichever is the optimum ph for the enzyme that breaks down the food in your mouth. So cm is the only way of testing. Lots of women use the PHion brand and you can get those from ebay or amazon and also some health food shops.
I think ttc a boy is probably more romantic than ttc a girl lol. At least you both get to orgasm and also get to do better positions

. All my boys were conceived in a girl on top position. (sorry TMI)
