I feel randomly horny today/high sec drive for seemingly no reason but the Eve app says I’m done ovulating

Hi guys! So basically I’m apparently finished my fertile window yesterday and now I’m leading up to my period in 12 days and apparently my fertility is low. But I started to feel strange today like I kept wanting to think about sexual things but I did not have the urge to masturbate at all. My mind just keep going to things that make me feel some type of way emotionally (but I can’t just masturbate and be done with it). And I dont necessarily want to be thinking this way I want to focus on where I am. And I don’t have a crush, I’m on a trip with only family and haven’t even seen anyone outside of my family for a bit so I couldn’t have a crush lol. It’s weird and I wonder what’s causing this. Could the eve app be wrong or is it right and there’s another explanation
