Confused on ovulation

Question...glow is telling me I ovulated yesterday but my body was telling me I ovulated Monday. I had cramping and little bit of pain only on the right side by my hippish/ pelvic area. Lasted about 5-6 hours and then I've been fine every since except for random cramping (not bad at all) on and off. My nipples are very sensitive and yesterday I got a little bit dizzy. Not sure what's going on or when I should count dpo. Help please.
