Timing to get high sperm count

[MyGlorylife]

So I normally O around 11am on cd15. Last month though it was like 4am on cd15. So we are abstaining right now to up the sperm count. I was thinking of dtd tmw night (cd 12) and then again on Saturday night cd 14 so that the sperm is in there when I o Sunday morning )will prolly hit Sunday morning too for good measure .
Does this sound good or should we I stain u Gil Saturday night?
