Does ferning mean I’m ovulating?

When you see ferning throughout your sample, it indicates the beginning of your fertile window. Differing from LH-measuring urine tests, ferning is a response to your estrogen hormone levels, whereas LH rises about 12-24 hours after estrogen spikes. OvuScope does not confirm you are ovulating or did ovulate. It’s a predictor of when ovulation may occur. Typically, ovulation should occur 24-72 hours after the peak ferning pattern appears. During/after ovulation, it is likely that you won’t see any ferning at all
