Any advice please..

I got have gotten to faint positive tests one before my period and one after. Af was due the 29th I had cramping two days before af was due and the day of.. I figured I was going to start.I'm never late. I went to wipe this morning and had light pink blood on my toilet paper.. Normally it's darker if It was a period. I'm not bleeding anymore. This has never happened to me before so I don't know if anyone else has experienced this but got a negative test this morning.
