This is a thing. You do it every other day starting on CD8, then when you get +ve OPK you do it that day and the next two. You have a "rest" day (ha!) and the next day do it once more for luck.
Anyone tried this? We went for it every day for a week last month and I think it knackered DH's swimmers. And the romance.
Going to give this a go along this month with copious amounts of Conceive Plus...
