It makes no sense

Maria

I have two different <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period apps</a> where i keep in track of my cycle and ovulation & i soo hate it that in this app it shows me that am 3 days late on period and the other one it tells me am actually 5 days late and at the end of the week I’ll still get my period makes no sense! Soo stressful.
