Am I pregnant?

Amy

I took a pregnancy test on the 1st and it was negative and then I started my period on the 4th. It was very light and lasted one day. My periods are normally 4-5 days and a lot heavier. I was thinking maybe I took the test too soon? I never have a one day very light period. I’m not sure if this means I still could be pregnant. Has anyone had this happen before? Thanks!
