Ovulation question

Karah

I am confused on ovulation a little bit. My husband and I tried around noon on Saturday and I feel like I am still ovulating today and it’s around 3pm cst. If we timed ttc for gender ( a girl) would you count how many days you tried when ovulation is over. So if ovulation ends for me later today, would that be a 2 and a half day cut off? Or a 2 day cut off since it technically started today? Confused on when my “cut off” day is. Thanks.
