So weird

So 2 days ago I went to the bathroom and saw a little dot of blood but it was extremely small & looked more like stretchy blood and dark but keep in mind it was really small. Also yesterday I smoked with my husband & i smoke weed here and there and I threw up and I was so dizzy and I couldn't stand up by myself let alone walk. I felt myself faint. I only smoked very little maybe one little hit. What could this be ? Please no judgement 💛
