raincloud, if yours is a 28 day cycle then u can start testing on CD11 onwards. Faint test line compared agst the control line means your ovulation is arriving soon but not that strong enough yet. If kiasu, can start BD on that day itself lor and do OPK test again on CD12 and see if the colour gets darker. It should get darker as the pass goes by till the day your ovulation will take place 12-36hrs later.
Jandew, have u started testing with the OPK today? I am sooo tempted to try. LOL
Oh yah, ladies, for those who are interested to get Pre-seed, DH and I just bought ours from Guardian at Northpoint. They still have about 4-5 bottles left. It's S$32 something. FYI, if anyone wants to get it [IMG=http://www.singaporemotherhood.com/forumboard/clipart/happy.gif] They placed it near the pharmacy counter so if u can't find it at the usual lubricant shelf then try it at the counter in front of the pharmacy area.
