TTC. Ib question.

Kelly
On 6 dpo, and ONLY on that day, I had spotting. It was sort of pink, but BRIGHT...almost red. Kind of nauseous and crampy that day and now the 2 following days. I didn't have implantation bleeding with my first (who is almost 6 yrs now), so idk much about it. Could this be it? Or is it more likely my body just trying to psych me out? Any ideas?
