sooo confused 🤷🏼‍♀️

I'm so confused on what's going on. I went to the er for a kidney infection and they asked if there was any way I was pregnant, I said yes. So the doctor checked my urine and said my hcg levels weren't high enough for it to be positive. My period is almost a week late with no sign of it what so ever. No cramping, bloating etc. I had very light spotting earlier this month that was a light shade of pink. I've taken two home pregnancy test and they both came back negative. Should I wait a little longer to take another? Like I said earlier I've already been to the doctor. If I could please get some insight as to what I should do, it would be greatly appreciated lol.
