First time using OPKs. Any insight?

Sarah

Okay so I recently stopped taking birth control pills. Had my first period after stopping on 8th of November. Had unprotected sex on the 14th, decided to take a dollar store opk the next day just cos. The top picture is that test. Bottom picture was three days later. Was I ovulating that early in my cycle? The app says top one is positive. 🤷🏻‍♀️
