I do not think timing sways a bit and in fact it's been debunked about as thoroughly as it's possible for anything to BE debunked scientifically speaking. What does seem to sway is more than one attempt in the fertile window which you DEF had several!!! That BD on O Day was the least of your worries.

My advice is to not worry about timing and just have one attempt in your fertile window. Worked for me after getting 3 boys with cutoffs!! Most of us aim at having 1 attempt one or 2 days before O simply because it's a good day for conception. We can also just have unprotected sex every 4 days and this averages out to be one attempt without having to think much about it.

I can't comment on hubby's supps without knowing his age and health status - LR in particular is rather dangerous so I can't just give a blanket prescription for that.
