Hi LifesGood, thanks so much for your interest and help!
I'm pretty sure it was the CD31 that FF took my CH's away. Most likely because of the 97.0 temp I entered?
It went like this:
CD 20/ 96.2
(Huge dip)
CD 21/ 97.0
CD 22/ 97.1
CD 23/ 97.2
CD 24/ 97.3 (
Got CH's as this being my fourth high temp in a row that FF detected ovulation as being CD 20 and gave me a cover line of 96.9)
CD 25/ 97.2
CD 26/ 97.3
CD 27/ 96.8
(Dipped below my cover line, a first for me, as I never had a dip below my cover line in all my ttc charts, ever! I was excited as I thought this was an implantation dip as I still had cross hairs at this time and was 7 dpo, it looked perfect!)
CD 28/ 97.0
CD 29/ 97.1
CD 30/ 97.2
CD 31/ 97.0
(FF takes the CH away!- Discard the temp to get CH's back, did a OPK got a positive and entered it in my tests data.)
CD 32/ 96.9 ( FF takes CH hairs away again!)
After I discarded the temp right away and got them back. But then the next day I got a 96.9 and FF took them away again!
SO...I decided to not discard the any temps and left them in.
However I never thought about what would of happened had I took away the positive OPK, maybe I could get them back somehow!
But if CD20 was really my O date then wouldn't I have a BFP by now? Here I am on cycle day 36 or 16 dpo and I am testing with a BFN. (I did a hpt yesterday on CD 35 or 15 dpo if I had my CH's.)
So it's really strange and I really do know what to think. Is there anything I can do to get my CH's back or does it look like I have not ovulated yet. I remember JM member Spyctre's saying that perhaps I was gearing up to O and then body changed my mind.
And being that I have never had CH's taken away or had a dip or dips below my cover line before it really confuses me and things are looking bad, like annovulatory!

What do you ladies think cuz I'm really losing it this cycle?
By the way...if you click on my ticker it should show you my FF chart.
