ttc and cm

Angela • 🌈🧸due 12/14/2020

Hi, I'm very new to this TTC thing. I am approx 3dpo according to my apps. for the first time this month today I have alot of cervical mucus. I thought this occured during ovulation. is it supposed to happen after? what could this mean? I'm wondering if my <a href="https://play.google.com/store/apps/details?id=com.glow.android">ovulation calculator</a> is off?
