Ovulation day

Alicia

It seems like my ovulation date isn’t matching up with my ovulation kit, it said my ovulation day was on Saturday but the kit told me I was ovulating on Thursday...how do I figure out what the true date is? I edited my app and we did the baby dance, so I hope it worked, but we didn’t have sex every night because my husband is a firefighter and he works 24 hour shifts.
