Can you have a slight temp rise before O day?
I know that your temp rises AFTER O due to progesterone, but today I got the highest temp I have had all month- just by .2 degress F but still the highest...I have had neg OPK's all last week and today though today's was noticably darker so I am getting close to O...just curious if anyone has any insight about pre-O temps...
I know it's common to get a temp drop the day before O and then the rise on O day...so I guess I'm wondering about the days leading up to that...
Progesterone begins to rise just before ovulation, so it's possible for the rise to begin before O. However, it's also possible for your temps to take a few days to "react" to the increased progesterone after ovulation. So the temperature pattern does not tell us the exact day of ovulation, there's a margin of error of a few days. It gives narrow estimate, but still just an estimate.
Also, individual temps can be affected by MANY outside factors (extra blankets, alcohol, slight illness, mouth breathing, varied waking times, etc.) So don't read too much into any one rise or one dip. It's the overall pattern that matters.
