Which day did I ovulate?

Jessica • DD 18,DS 14. Currently doing IVF; FET January 2020.❤️🙏 Baby boy due fall 2020

Okay, I know I have to have at least 2 more days of high temps for ovulation to technically confirm ovulation, but going off of what I have so far.... would you say I ovulated Sunday or Monday? In other words am I 1dpo or 2dpo? Thank you in advance for any help or advice.
