Ugh what in the heck

Periods late pretty sure was supposed to start the 29th but glow kept changing it because of all of my negative opks. A few days ago I took a test and a vvvvvfl showed up and I took one the day after and also one yesterday and it looked like the line disappeared. I have been having spotting off and on since my last period ended. I have no idea what the hell is going on.
