I'm just wondering, if you were ttc a boy would you only do the deed on peak days and not the high days leading up to peak days? Presumable the high day after the peak would be ok?

Bit of a niche question I know!

I conceived my dd the high day after my peak!

That's interesting engelbart, thanks!
