Hey Laurel!!! I am glad you desided to join us

We are hostless (our old host recently got a BFP

) and pretty slow but none the less this is a great board and the ladies are really sweet. You will see a lot of the AP mommies here
About charting....since you have no AF chances are you are not Oing at all. But you can still chart your waking temp daily and look for signs that you may be returning to fertility soon. Plus it is good to just practice that way you and DH will be old pro's once you do get AF back.
Do you know what method you will be using for charting? There are a couple differnt types. Sympto-thermal method is that I use...where you temp and check your CM and cervical position. Billings Ovulation Method follows mainly fertility signs and I don't think they temp, could be wrong. And there are a couple others...these are just the main two.
Once Lincoln starts eating more solid foods and nursing less I bet your AF will come back.

welcome to the board and GOOD LUCK!!! We are NTNP too
