OPK Negative But Ovulation Symptoms

Q: I have a negative OPK but ovulation symptoms. Is it possible that I am ovulating?

A: Even though the OPK shows no LH and is negative it is still possible to ovulate. The LH test is not the best way to determine exactly if and when you ovulate. Sometimes the OPK is only positive for 8-12 hours, so if you test once a day it's normal to miss the positive test. That's why it's recommended to test twice a day every 12 hours.

A better way to determine ovulation is to do a basal body temperature curve. If you have all the other signs then you can assume you are fertile. Make love every day or every other day during the week leading up to ovulation. Don't wait making love for the LH to first become positive. You may miss it and decrease your chances of getting pregnant.
