What are my chances??

The plan was to wait to TTC until October. Last night last minute we decided why not this month 🤷🏼‍♀️ according to an app I have my ovulation day was yesterday. Checked today and my cervix is still high and open. Do I have a decent chance? I feel like I'm already getting my hopes up and will be so bummed if I get a BFN 😔
