There's really no way to tell. It generally isn't a gradual increase before a peak. The peak happens pretty quickly once it starts. This could be an indication that youll peak soon, but you might also stay at this level for a while first. Just keep testing.
@Taylor I was running out of tests so only was testing once a day and it’s lighter today so I’m thinking I reached the peak but no way to tell.
Are you taking your basal body temp? It doesn't predict ovulation, but it can confirm once you have, which can be helpful. I'm not sure I would assume that you peaked between tests just because it's lighter now. Before your peak there can be natural variations in LH levels.
The next day mine was way dark so may by tomorrow
