way OT: For those who chart cycles

I am wondering if anyone here charts there cycle and has experience in weird charts?  You know things are going normal every month and then all of a sudden your month is not normal.  I have a teaching couple who is helping me but I always like a second opinion on matters.  If you chart and are a teacher or very knowledgable in this area and might have time for me to bounce my chart off to you I would appreciate a PM.  I have taken the NFP class.  Thanks Misty
