Implantation bleed or weird period?

Siobhan

I’ve had every symptom going this month and am now 11dpo. I started with a tiny amount of pink spotting then brown spotting late on 9dpo then yesterday had a hint of beige brown discharge in pants and when I went to the toilet had some pink/brown run into toilet bowl when I went for a wee so figured period was starting. This morning I had some pink/red in thick discharge which was mainly normal colour and since then nothing. Nothing but normal thick CM. Pregnancy test this morning was negative and I’m so confused as to what this is 😩
