Is eve right about my period date?

Taylor

Do you think <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> is right at the day it predicted I’d get my period? I feel like last month was just a unusual period and maybe I should be expecting it 10th or 11th like the other months? I had unprotected sex (pull out method) two times this past month so I’m wondering if I need to take a test or should I wait until Monday and see if by period comes. What do y’all think?
