How will i know from temperature spike?

Question

What will my temperature spike up to when I am ovulating? And when it does- how much time do I have?

Answer

So the BBT chart is great to know if you ovulated after it already happened. When ovulation occurs you’ll see a spike of at least 
0.4 F, and is going to stay elevated. That’s how you know you ovulated. 
The egg is good for about 24 hours, that’s why the best way to track when ovulation is going to happen is with the OPK’s; once you have the positive result, you’ll ovulate within 24-36 hours. If you have sex during that window you will increase your chances of pregnancy.

Answer

Typically by the time your temp rises, the egg is dead and gone or already fertilized. That's why you shouldn't rely on bbt to tell you when you'll ovulate. Opks or tracking your cm would be better at predicting.
