First month TTC, need some guidance

First month TTC, need some guidance. Took ovulation test 9:30am the 23rd, CD 22. It was positive, noticed cramping to left side that night around 8:45pm, assuming ovulation cramps and that I ovulated from left tube. Do I consider ovulation day the 23rd or the 24th? Glow has it down for the 24th? Lmk what you all think.. Look promising? My avg cycle is 35/36 days.
