Help!

Hello! I know you’re supposed to wait until the day of your missed period... mine should be starting in 4 maybe 5 days but I’ve been very crampy tired and cranky all week. I took a test just because..... and I feel like my eyes are playing tricks on me. It looks like an incredibly faint line it’s right after I peed but still don’t believe that it’s actually something? Does anyone see it or am I crazy? Its also late in the day and I’ve drank a lot of liquids today..
