I was feeling very confident about this cycle until this morning! Idk why. Maybe it's because my temp dropped again. I hate this BBT thermometer I purchased off Amazon. It's a good degree less than my other normal non BBT thermometer, and I noticed if I take it like three times in a row, temp keeps going up.
Can anyone give me insight on my chart and ovulation? I definitely feel like we started BDing too early:/ Good luck anyone testing today!
I had a similar temp drop on what I presumed to be 3DPO. A google search suggests that it may be a corpeus luteum dip. It is caused when the estrogen drops as the corpus luteum takes over and starts producing progesterone. Estrogen drop causes BBT drop. The next day your temp should rise because of the progesterone being produced by the corpus luteum. It is normal and can happen in pregnant and non-pregnant cycles.
Hope that helps! You can compare to my chart, where I think I Oed on CD16 and then had a dip on CD19. FF won't give me cross hairs yet ... so I'm waiting to see what it thinks after a few more temps.
