Another period?? What’s going on?

I got my period on Jan 3-8. I experienced some light light pink spotting on the 18/19th when I believed to be ovulating so i thought it might be ovulation spotting. But on the 21st I wiped it was red blood. I put on a pad that night and it was nothing on the pad , only when I wiped I saw blood again. I have been sexually active. What can possibly be going on???
