CONFUSED ABOUT OVULATION

so girls I’m kinda confused about the ovulation days and discharge, in my fertile window I usually dont have any discharge but right after it finished I have a lot of discharge and I feel frisky so I dont know if I’m fertile during that time or it doesnt matter cuz

my mom said to me that I’m fertile when I have that discharge but <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says that I’m not 🤷‍♀️
