Abstinence and birth defects

You could use Rephresh every 3 days to bring pH down but it would need to be absolutely every day - not pretty much every day! Personally I'd have DH release throughout AF before we started BDing to make sure sperm count was low enough before my fertile window.

Or would that raise ph too much?

It might but I would just use RepHresh pretty frequently - even as much as every other day - to keep that under control.
