Nic, have you tracked your pH? It won't matter too much if you get close to O if your pH is low enough. Make sure you get loads of BDing in before your attempt... it will help lower DH sperm cound and also HOT showers/baths for him
Tanya, for a boy, does your PH need to be slightly higher? I tested mine last month around O and it was on the high side of 'normal'. but I'm now confused if that means my diet changes have done what they're supposed to or not.
