😡 Frustrated

I wish I got into ovulation testing. My periods are so regular that I assume I ovulate around the same time each month. I've done so many ovulation estimation calculators, have different apps to see what days they say my predicted ovulation day is. They all range from the 19th-23rd. Which is good news because I definitely had sex before during and after those days, so I wouldn't miss my ovualation. I just hate not know the exact day so that I'd know how many DPO I am. UGHHH. Some day I'm 9 DPO some say 11... I don't want to symptom spot, I just feel exhausted overall. Slightly dizzy too. I don't know if it's too soon to feel that way though.
