Whats goin on?.?.?.?.?.?

I had a wonky "period" last month. It was a week and a half early and was very light. And going off the first day of that, I would have been due for my period on the 4th of this month. But I haven't had any signs of it showing. Rather I've been having pregnancy symptoms: nausea, breast tenderness and they're swollen, thirst, which leads to excessive peeing. But I just took an equate pregnancy test which came out with a faint -. (Positive would be + on this test). I don't know what to think
