Weird period TMI maybe

So this month i really thought i was pregnant. I normally have pretty strong PMS symptoms but this month i didn’t. I also had different symptoms then normal. I was also 2 days late so i bought a test on what would’ve been the third late day to take the next morning. Well AF showed up before i could take it. Normally my period comes on with a vengeance like to really let me know I’m not pregnant lol but this one was extremely light the whole first day. Normally it’s really heavy days 1 and 2 and i have horrible back and stomach cramps but this month, it has been WAY lighter than normal, no cramps and it’s been really brown blood. I felt like that pregnancy test was just staring at me so i took it on my second period day just to get it out of my system and feel ok about throwing it away. I didn’t even look at the results because i knew it was gonna be negative. I didn’t throw it away though because i really like to taunt myself 🤦🏻‍♀️ i looked at it this morning, 3 days later and it’s positive. I know it’s not a valid result because it’s way past the 10 minute window and it’s more than likely an evap line. But there is a small part of me that wants to test again because of how weird this period was and I’m still really nauseous and dizzy. Am i crazy and just getting in my own head? Or is it worth spending the couple bucks to test again?
