Niass, you can buy pH sicks on the net... I got mine through ebay (USA).

Timing didn't work for me either I know of lots of girls who have gotten girls who have BD'ed through O.

DH'd semen should be lower for a girl... 9+ for a boy (sorry can't remember what exactly for a girl). So he may need to change his diet to decrease his pH. There are also sups he can take. You may need to google it.

Also you can read back through this thread and the previous one it may give you lots of info
