Help!

So here’s the deal. I took the top test this morning, I thought I saw a vvfl, but just threw it in the drawer and walked away so I wouldn’t obsess over it. I came back this evening to look at it again and the test clearly has a second line (with color!) on it! So being excited I tested again this evening (I held urine for close to 4 hours before testing) and there isn’t any line that I can see 😞 I am supposed to start my period Sunday (8/4) but am going to a wedding Saturday and just really want to know before I go so I know if I can drink 🤪

I know you aren’t supposed to read the tests after the time limit but the line definitely has color and I didn’t stand there for the whole 10 minute time frame 😅😅 I’m obviously gonna test again in the morning! Just wondering if anyone has any thoughts!
