Hi I have been learning how to use fertility friend and have a question...

My periods are usually pretty constant and my last one was on the 19th of Nov. 07. Usually this means that by the 19th of this month I should have a m/s again. But the chart is showing me at the 25th of Dec due to a late ovulation. It is also telling me that I have a 36 day cycle. Is this normal or is it just because my chart is still new it has not adjusted yet? I am just a little confused because I was expecting it to start today and have had nothing but have always thought it is every fourth week on the dot. DOes late ovulation do this to everyone? Or can it be my cycle is just changing du to a recent m/c....I have also just started taking my temp too and recorded a very big "dip" on cd7 but it went back up on cd 8. I read somewhere that when you see this you m/s is not far off. How accurate is that and also does everyone experiance this? Sorry just a little confused. Thank you guys in advance for your help.

I included my chart so you guys can see what I mean by the m/s date and o date with the temp thing.
