Quick question.

I have <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> and Flow, and I use both to track my periods and to see when I am ovulating. I’m trying for my second child, so keeping tabs is obviously key. However, my Flow app is telling me I have been ovulating as of yesterday, while <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> tells me I won’t ovulate for another 2 days. Which should I go by? Both have my periods logged on the same days...my husband I had sex day before yesterday, so I’m trying to see how fertile I actually was...help! 😭
