Hi everyone .. I’m in search of some answers and/or opinions

According to my Flo app I ovulated on April 28th but according to other resources it was the 29th . I had a positive OPK stick on that Wednesday. It was my first time using them ever on that day and it just so happen i was at my peak ! I did the baby dance on the 24TH and 29th. According to flo , my fertile window was from April 23rd-29th. Is is possible that i could’ve conceived this cycle? I DTD 4-5 days before ovulation. My cycles are also regular (28 day)
