Please can any one help, I am now into my 40th day from my the first day of bleeding from my last period. That is my cycle seems to be much longer than 35 days. How do I work out my ovulation time with them being so long?

I am only just getting the symptoms that I will be due on tender breasts, moods ets. Is it normal to have such long cylcles? and how can I work out when I am ovulating if period cycles are so long?

Thanks
