Should we do it again?

What atomic said!

If you were trying for a boy, you would have been BDing every other day since AF then once you got a positive OPK, you'd BD that day, the next morning, and then again at night, then skip a day and resume every other day in case you Oed later.

Thanks maidentomother. Why do you need to BD every other day for a boy from AF if sperm dont normally live longer than around 4 days? (If that's right?) Is it to do with changing of PH or something?
Sorry for all the questions, just want a better understanding of all of this as I find it interesting.
