what could it be?

Nadine • Ttc since tubal reversal August 2016
I took a dollar store test today and I see a faint without squinting but then I went to bathroom n saw a little pink blood with creamy cervical mucus. I waited an hour and peed again and wiped but no blood. I took a clear blue digital n it said not pregnant. My period is due today. Could it be implantation? Please help me
