What is this?

I took this 5 mins after the test was done so I know it's not an evap.. Thought it was probably an indent. In person I can't really see it unless I turn the test a certain way. It showed up better when I took a pic. I don't think it has an color. Really the chances of it being a positive are crazy small because I would have convinced the 1st day of my period. I'm feeling a little off but not too much. I should be ovulating right now.. So I'm not putting much thought into this being a positive.. But I wanted to see what yall ladies thought. I'm on meds I can't take if preggo and I don't want to stop them unless yall think this is viable. Thanks ladies :)
