Yep, you need to get the CM from your cervix... CB, no change on the strip is probably a good thing because it would indicate your pH is low.

I O'd later than I had hoped... I think yesterday (Sun) Morning... we BDed Sat afternoon... not sure if that was too far from O but I paniced when I saw an almost ++ OPK on Friday morning. I tested again about 2pm and the test line was almost GONE! Tested again at 5pm and the test line was soooo close to being ++ that it could have been classed as a ++, I was sure that O would be the next evening... I didn't get any difinitive O pains like I do sometimes (such as last cycle) SO I am thinking it may have occured while I was sleeping. Dunno... too late now! LOL
