Hi girls, I'm a newbie to BnB aswell. I have been off the pill since last September and have been charting my temps, CM, and CP. I really recommend charting. I have really gotten to know and understand my cycle. DH and I are on our 3rd month of TTC. I decided to try the OPK this time around just for fun. Sure enough they work! I'm on CD 12 (the beginning of my fertile days) of a 30 day cycle and I got a faint line so my LH is starting to surge. So if you are going to use them, I suggest you learn your cycle and try to figure out when you should O and then start using them a few days before you think you are going to O. That way you save money. We already have to buy all those preg test now adding OPK to the mix can really add up! Baby dust to all!!! Here's hoping for an April baby
