I need advice...

I didn't have a proper period, was 4 days of spotting brown. Not even heavy enough to stain a pantyliner. So now I'm counting it as over 2 weeks late for my period. I always bleed super heavy when I have my period. I took a hpt for shits'n'giggles and got this about an hour after I took it. I checked the test and it was still soaking wet so I don't think its an evap line... Thoughts??
