Has anyone else received the wrong ovulation date ,and actually felt when they were ovulation or having the M Cramps on the right side along with cervical mucus .

My Actual date of the egg traveling was MLK DAY 21st so I actually ovulated the day after ,

Now here the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> says the 23rd which is incorrect and now , I’m spotting pinkish discharge when I use the little girls room, and my side is hurting as if I’m ovulating again but with minor cramping ...

Never experienced it before ,Can Anyone else relate or had this happen ,including the date being incorrect???
