Weird period.

Jasmine

So I got my period and it was normally heavy for 2 days then randomly I just started spotting for the next 3 days. I took a test and it was BFN but I thought it had a faint line and I took another one this morning and instead of it being 2 vertical lines showing up on the best it was horizontal for one?!?! Anyone ever have this?!?! Should I just wait and test again in a week?!?!
