ovulation strip analysis

hey ladies! these ovulation tests were taken 2 days apart. according to my app when i took the first one i was at 7.8% chance of pregnancy and when i took the second one it said 9% chance of pregnancy. personally i do not think that adds up but i’m new to the ovulation test strips so i just wanted to hear other people opinions. i had unprotected sex twice on the same day as the first test. i am not looking to hear anyone say the app shouldn’t be used as birth control because i clearly know that and am careful when i want to be. i went into it knowing there was a chance. thanks!!
