When did I ovulate?

Christie • 29 years old. TTC since September 2013.
Here is a pic of my ovulation tests. Do you think I ovulated on 2/22 or 2/23? My husband was out of town so we weren't able to BD until 2/20 which was CD 12. I usually like to BD several days prior to ovulation and I usually get very clear cut OPK results but this month it was a lil fuzzy. Any input would be appreciated, thanks! (All were taken in AM with first pee)
