Lionessmom, a temperature jump like that usually means ovulation, not necessarily pregnancy. You'll want to wait for 3 days in a row above 97.4 before you assume that you are infertile, or really, if the next 2 temps are definitely "elevated," you could use the 5 day temp only rule, but that's looking pretty good. I think you may have ovulated around CD 21-24, so pregnancy would be dependent on what happened during and shortly prior to that time frame.

Butterflymomma, I would agree with jodi and wait a little longer to consider yourself infertile. This is exactly what I meant on the other thread when I was talking about it being harder to tell disturbed temperatures that look like a temperature rise. Things will become clear in just a few days. I really have no idea what TCOYF is "thinking" on this one. If yesterday was Peak day, you're likely looking at Sunday evening as your first infertile time. (Depending on what temps so and how sure you are about them being accurate, we may be able to call you infertile Saturday night, but if you're wondering about temps, I would wait until Sunday if you continue to experience higher temps and CM dry up.)

A note on OPK's: They are helpful for some women, but I don't think very highly of them for depending on them. I've seen a lot of false positives on women whose bodies try to ovulate over and over again in a cycle, and every time they try to ovulate, they get positive OPK's. It's also very possible to miss the LH surge. Some women have a lower LH surge than what the test calls positive, and some women have such a quick LH surge that they would need to be testing many times a day to get a positive result. Just because you did not get any positive OPK's does not necessarily mean that you did not ovulate.

Jodi, it looks like CyclePro is calling CD 17 Peak day, and I would agree based on your TCOYF chart. It looks like you had a double peak with the first peak looking more fertile, which is not terribly uncommon, but the second peak is usually the one associated with ovulation. I know several people who have conceived babies on their second peak because they didn't wait enough days of dry up. Also considering that while you had a nice temperature rise, your temps seem to be in a falling pattern, I would give it another day just to be sure.
