How do I confirm I ovulated?

Bottom lineConfirm ovulation after the fact with a sustained basal body temperature rise (about 0.3 to 0.6°C) lasting until your next period, a raised progesterone blood test about 7 days before your expected period, or a predictable period roughly two weeks later; ovulation kits and fertile mucus only predict ovulation, and no temperature rise over several cycles is worth discussing with a clinician.

Ovulation predictor kits tell you ovulation is about to happen, but they don't confirm an egg was released. A few methods confirm ovulation after the fact.

Ways to confirm

• Basal body temperature: a sustained rise of about 0.3 to 0.6°C that lasts until your next period is a reliable after-the-fact sign
• Progesterone blood test: a clinician can measure progesterone about 7 days before your expected period (a "day 21" test in a 28-day cycle); a raised level confirms ovulation
• A regular period roughly 2 weeks later: the predictable luteal phase following ovulation is itself a clue

What kits and mucus tell you

• A positive ovulation kit shows the LH surge that precedes ovulation - it predicts, not confirms
• Fertile cervical mucus signals the fertile window, not that an egg was released

Putting it together

The clearest confirmation combines a temperature shift with a predictable period afterward. For medical certainty, a progesterone test is the standard.

If you track for several cycles and see no temperature rise, you may not be ovulating - worth discussing with a clinician, especially if trying to conceive.

Femora helps you log temperature and period dates so you can see the post-ovulation pattern that confirms it.
