hey - thanks again sal - you seem to be answering a few of my questions lately... Yea i am yet to see a positive OPK - so have given up - at $45 a cycle its too expensive... i am still learning about CM as well - i don't understand that really either especially when bding - can't tell what is what - so am relying on temps -and even those aren't reliable for me right now as i am not sleeping right with our new puppy...
