well, i've looked at all the pregnancy & ovulatory charts that are posted on the fertility charting board many times. i don't think i saw anyone that their temp went down & then up closer to af. sounds like it could be a good thing. i hope it is!! when is af due for you? i would test. but that's just me

cd 16 does look like it could've been o day. it probably put the other day cuz it looks like you put in ewcm, right? did you have any ewcm on cd 16? if not, then it was probably the other day that you o'd. good luck!!
