App confusion

Why does this app keep telling me I’m ovulating on different days within my cycle? This has been happening for a few months. It said I was ovulating two days ago and sent me a notification to use extra precautions, and now it says ovulating in 4 days?? I don’t have any conditions that would cause ovulation to happen multiple times a month like that so I’m wondering if I did something wrong in the app??

I am not putting in any data that could be indicating fertility or anything that would cause an irregular cycle, so I’m not really sure why it’s doing this. Maybe I will just contact customer support or something to see why it’s doing this. Thank you!
