My lh level is 21.6 does that mean i have already ovulated or about to ovulate?

3 possibilities: A single lh value must be taken in context of your age, history, and where you are in your cycle. If you have polycystic ovarian syndrome (pcos) , this level could be present at any time. Likewise, this can be true in the perimenopause (yes, a possibility even at your age). Most likely, however, this indicates the midcycle surge that triggers ovulation in the next 24 to 36 hours.
