Did anyone experience this?

I have been TTC#1 for 5+years.

I usually have a luteal phase of 14 or 15 days after ovulation.

This cycle i am only 12dpo and started very little brown spotting. I am on progesterone supplement after ovulation as usual.

So is it an early period or implantation bleeding?

I know it is very rare and on Google i found that implantation bleeding can be pink or brown.

I am just curious since i gave up hope when i got a bfn yesterday.

Anyways this is my first time experiencing a spotting so early. I have been on progesterone previous cycles also, so i don't know what's happening.

Anyone had an experience like this and got a bfp??
