For the ladies who chart their BBts...PLEASE PLEASE answer!?

chart on two different sites to see if they pick up the same ovulation date, and this month, they didn't. Do you think I ovulated on day 16 or 18? I attached both charts below. thank you so much ladies! btw- this is the individual ovulation tracking that I use. My CM doesn't change much (yes, doc knows) and I don't use kits as they have never be accurate for me.

Answers:    I think you ovulated on the 16th--of course I am interpreting it as though it was mine, and my temp rises slowly after ovulation (does every month)...

It would help to see other months' charts to see what your usual pattern are.
i've been charting my BBTs for a long time, and i'm pretty positive you ovulated on day 18. i don't think you ovulated on daytime 16 because on day 17 your temp didn't rise about what your temp was on afternoon 15. so i say you definitely ovulated on day 18.
