Mrs Ho: I tested DPO9 but BFN. Then I didn't test again until DPO13 (yesterday) and DPO14 (today) when I got the faint positives. My cycle only 25 days, so I think i O-ed earlier than you, probably around CD 10/11. My BBT are like these:
Follicular phase: hovers around 36.5. But on CD10, dropped to 36.0, which led me to think that I O-ed on that day, cos sometimes O will cause temp dip.
Luteal phase: 36.7 - 37.2. After DPO9, hovering around 37.0. So perhaps I implanted on DPO9, cos supposedly after implantation, temps will rise further...
Anyway ladies, just to share my TTC-ing methods FYI. My supplements: follic acid, royal jelly, evening primrose (CD1-ovulation for better CM), cod liver oil (after ovulation)
DH supplements: folic acid, royal jelly, cod liver oil, Immuvital, Coenzyme Q10
I usually BD on O-5, O-3, O-1, O day, O+1. I have a retroverted uterus, so chances are better if i lie on my stomach instead, with a pillow propped under my upper thighs.
And I use Pre-Seed.
That's about it. Sticky babydusts to all, including myself!
