Implantation Bleeding?

Trista

Hello,

AF arrived on Feb 18th and ended on the 22nd. I started Clearblue advance ovulation on the 25th. On the 27th it came back as High Fertility, as well on the 28th, March 1st and today. I still have not received a Peak High (Non Blinky Smiley). Today I had some Pink blood on my toilet paper when I wiped & i have mild cramping.

Is it possible that the test didn't pick up my Peak and it's implantation Bleeding? It's not normal for me to bleed/spot in between periods.
