I would personally start at least 3 days before you expect your first fertile day. I've read before to start testing around CD 10. The first month I started using OPK's I started around day 6 I think, because I didn't even know when I ovulate or even IF I ovulate due to PCOS. I used Internet cheapies so I had a bunch of tests. Anyways, that month I O'd on CD 9. The next month on CD 8 and again between CD 15 & 16, which is what I got pregnant from (the second time I ovulated that month).
