Ovulation Help

Cl

So for some reason I'm having Febs period in January. So I've had 2 periods this month. I have both <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> and Glo and they're a day off. What days do you think I should have sex for the best chance?

.

Also farther down the calander it says I ovulate twice in one month?? That is pretty far away so I'm assuming that will change though.
