I've been pretty bad at using aids to track my ovulation so far but I have a regular 28 day cycle and physical changes that indicate ovulation around day 14 are always present. I have noticed a funny thing though each month. My libido tends to sharply increase around day 10-11 of my cycle - it will the strongest at this time of the whole month (and I have the most intense orgasms at this time), while at days 12-14 when I should be ovulating it's not at strong. I have been TTC for a year, late thirties and I know that I should be doing a better job at tracking my ovulation, I just wondered if anyone else has this experience? Is there a link between spikes in libido and ovulation I wonder? I'm beginning to wonder if I am ovulating a little earlier in my monthly cycle instead of between days 12-14.
