First time poster looking for a little help working out ovulation please :)
I stopped taking cerelle on 1 January and started using Natural Cycles TTC#1 aged 30. I had no withdrawal bleed, but very light spotting on CD10 and 11. I've been tracking BBT since early January, and Natural Cycles tells me I ovulated on CD18 - I used ovulation sticks as recommended on CD11, 14, 16-22, and never got a positive reading. However, my temperature spiked at CD12 and remained high after that.
I've since had a true AF (unless withdrawal bleeds are as heavy and painful as normal AF?), and am now on CD10. What I want to know is, should I start using the ovulation sticks again now since the Natural Cycles App doesn't know my cycle very well yet? Is there a chance I either didn't ovulate last month (with coming off the pill), or that I ovulated much earlier than the app thinks? And should I be testing twice a day rather than the recommended once? Natural Cycles doesn't want me to use the ovulation sticks until CD16.
For background, I've been using the pill constantly for ~17 years, with a change from combined to mini 3-4 years ago.
I'd appreciate any thoughts on this from more experienced ladies!
