Confused

🌹Jackee🌹 • Mother and stepmother to 5 amazing kids! Im married to the 6th kid lol, we are ttc #6 for our family!.
So I'm supposed to be 8 dpo according to this app. I've been having sore breasts and cramping, fatigue and have been a bit moody. Af is due the 22nd. I've been checking my cm and today it's stretchy but also creamy. Wth!? Could I be ovulating a week before af? I understand you ladies aren't doctors but has anyone else have this happen before?
