I’m so confused!!!

I posted on here a few days ago with the below photo-a positive pregnancy test!

(I also had 6 more positive tests last week also-all different brands)

I was due on my period Saturday, which still hasn’t arrived.

This afternoon I’ve had a little spotting (only a little when I wipe) it’s very watery/diluted and pink/brown in colour.

Usually my periods are bang on time and are really heavy. I always have bad period pains at least 2 days prior to my period, however I’ve had nothing at all and I’m over 2 days late.

I’m not sure if it’s implantation spotting?

Has anyone else had this?

I’m so confused!!!
