Hi,
So we're still in the process of deciding whether we want to TTC, but in preparation I've been tracking my cycle over the past 6 months or so.
They are generally fairly regular - every 28-30 days, ovulating around day 12-14 and I can normally feel it quite strongly. I'd get 2 or 3 days of flashy smileys and then the static. However, the past two cycles, I've had empty circles and then straight to a static smiley.
I understand that when it flashes, it's indicating that your estrogen levels are rising, which is then followed by your LH surge, so if I'm not having that, does that mean my estrogen levels are declining? 
My 36th birthday is just round the corner and so I'm worried that my fertility is maybe decreasing. I did have a fertility test last winter and my results were very good, but I suppose things can dip at any time.
I just wanted to see how common this was.
Should I be worried?
Thank you
