Test or wait? 🤔

Period is 13 days late... 3 days ago I had 2 tiny clots but no period or bleeding of any kind with it :/ I'm trying to decide if I should test in AM or wait a few more days to be sure. Could it be implantation or maybe period going to start in a few days? I've been having symptoms but maybe they're just from "baby fever". Don't want to look stupid when I get another negative and my period comes the next day :(
