Hi I am the one who went 73 days between my 1st PPAF and my 2nd :O Between my 2nd and 3rd I went 43 days then it was 36 days and now I am back to my normal 32-34 day cycle.
Good luck with the OPK!!! I would also really recomend charting to see exactlly what your body is doing and when. After I had my 1st (DD) I did not O for my 1st couple of cycles. And after DS I know I did not O on my 73 day cycle.
If you need any help charting I would be glad to share what I know. Or the NFP board has a great sticky about charting while BFing as well as some really good links to informitive websites.
Make sure you KUP and lots of Baby Dust for you
