Red spotting / implantation. Please reply💕

Sa

Hello lovely ladies, at 7dpo I had the pink spotting, 8 dpo a bit of brown, 10 dpo (today) it’s dark red and heavier. I’ve been nauseas and headaches, snuffy nose, tired and emotional. I’ve been mildly cramping for a few days (since 6dpo).

Is the red spotting and heavier amount a sign I’m not pregnant?

Neg pregnancy test (but it’s still early)

AF due 13-14 dpo and I don’t bleed or cramp before a period.

I’ve only had an implantation bleed once before- it was pink one day and it turned into a chemical pregnancy.

Thank you. Impatient!
