Ovulation tests usually take 10 mins to fully develop so if it was in that timeframe go with the second one x
These are a day apart as long as you had sex on 05/04 or 05/05 you should have covered your window. You can ovulate anywhere from 12-24 hours after a positive test sometimes it's 48 hours.....Sperm can live in a female 3-5 days.
I’d probably take the reading of the first test as obviously that one was in the time frame x
