Discharge meaning

So I got this discharge July the 3rd which according to this app would have been the 11th day of my cycle the day before my fertile window began. I did some research & it said this type of discharge means you are ovulating.. which is confusing bc the eve app said otherwise. I’m really scared bc I stupidly had unprotected sex on July 6th(14th day) which would have been the peak of my fertile window but it said on the 6th I had a 15% chance? Also eve sent a notification to me today (the 9th) saying I was ovulating which contradicts the discharge I got on the 3rd.. I took plan b around 12 hours later after having sex. I’m just confused to as if eve is glitching or not or I read up wrong about my discharge
