Hi Deech
It must be one of those months, I am still waiting for my O, very strange for me. I got so paranoid here in Australia you can purchase a FSH menopause test from the Chemist which I did on Sunday and thank goodness it showed not in menopause or perimenopause yet!!!
I think it is stress of TTC for such a long period of time and if you are taking supps etc, I have found that my whole cycles have been crazy!!!
Good luck and do not give up . I am also going to try Acupuncture as I have heard excellent things especially for us mature mama's TTC. Although go to one that specialises in fertility.
