Change my O date?

I’m having a very long period, and am on day 13 today I think. (I’m losing track)

Anyway as I add yet another period day to my Glow calendar, my ovulation date moves forward as well.

So does a longer period push your o date further ahead as the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> seems to be doing? Or do you still O at the same time you normally would?

I’m supposed to be O-ing soon and am having zero symptoms when I normally have a ton of O symptoms.

So very lost 😔
