Period or implantation Bleeding

Hello,

Normally I wouldn’t ask but I figured I would give this a shot. I am suppose to get my period on the 9th and my flow is usually pretty heavy with cramping, etc. however on May 3rd I started bleeding it was first bright red when I wiped and I thought ok I got my period early and placed a tampon in, the next time I went to the bathroom about 3 hours later the tampon only had light pink and brown blood on it. Today the same thing so I put a panty liner on instead of having a tampon in and it’s been 5 hours and its only light pink when I wipe and barley anything on the panty liner, I’ve had some cramping but not normal cramps
