What is it? Spotting, Implantation Bleeding, or Period?

Hi ladies,

TTC baby #1 - I’m 9dpo and I’ve just started my “period” I think - but I’m not sure.

Yesterday and the day prior I had very very light pink/brown when I used TP. But today I felt wet and sure enough it was bright red blood. My period is due in 6 days.

I’m so discouraged and I just hate not knowing what’s going on.

Any advice?
