Different Dates 😭 Flo v. Glow?!

When I first stared tracking my cycle I used Flo, but then I found this app and love the community feature - so I’ve kept both apps..

But I’m having an issue - they both say different days for ovulation and period start date...even though I’ve entered the same period dates & cycle length!

Is there one app over the other that you feel is more actuate? I have OPKs and a thermometer for bbt but I haven’t been super dedicated to either yet.

According to Flo I’m 2 days late but according to Glow AF is not supposed to start until tomorrow 😑
