Good luck with your attempt, your plan sounds very good. By the way, re the preseed with BS, I tried this as well and I had to put quite a lot of BS to the preseed and can get the BS to 8.2. 4 pinches of BS is not enough.
@sway4son: sorry to hear that your AF came. How many cycle you have tried this?
to all ladies who are going to attempt: good luck to you all.
I just have a question, do you think the high pH (with BSF and/or EW) may have killed most of the sperm and that is why there has not been BFP?
