HELP... implantation bleed???

Hi,

I have been tracking my cycles and ttc for 9 months.

I am now 7dpo and period not due for another 9/10 days. Last night and this morning I noticed my discharge was pink tinged and today slightly brown tinged. My period has never arrived early in my time tracking and I am afraid to get hopeful that this could be implantation.

I have had dull period like cramps for about 3 days also.

Can anyone give me some advice or experience with this? I am really desperate and can't help but feel this could be it🙏🏼
