What is going on??

I just randomly seen this in my drawer and thought “wait a minute, that’s a line” I had a UTI on the 18th and started bleeding and passing some blood clots so I figured it was time for my period because I was due on the 19th. Should I take a test? My mind is racing and my lack of better judgment is thinking it may of been blood from the UTI 🤷🏼‍♀️ and why wasn’t the other one the same if it wasn’t a line? Ahhh so confused.
