Lower sperm numbers DO seem to sway and so for some people if they did have a long cutoff (which unless ovulation is confirmed by ultrasound, I strongly doubt that anyone got pg from a 7 day cutoff and would suspect that anyone who believes that they did, actually ovulated sooner than they realized - but I digress) that it was lower sperm numbers that swayed pink and NOT that X sperm are stronger or longer lived, because they aren't.
