Should I test?

Ok I had a period in November regular cycle usual 7 days..I was supposed to start this month on the 5th and started the 4th it was maybe medium flow but dark in color it lasted 2 days and then brown spotting for two days after. I've never had a short period or a lighter period. I always start with a heavy period an it stays heavy til the 5th or 6th day. I always cramp really bad and this month I only had cramping the first day. Took a pregnancy test the sat after it stopped but was still spotting. I still feel like I could be pregnant as I have signs and just feel off. So should I test again?
