When did you experience implantation bleeding in your cycle and ended up being pregnant?

Al

I am 11dpo, woke up to some brownish discharge when I wipe. I’m at least 3 days early for my period. I have longer than average cycles. Have started some v light cramping. Usually if it were my period I would have been cramping heavily well before. I have endometriosis so usually i have plenty of a symptoms before during and after. Pain is the sign to everything in my world 😩

Anyway. Curious when in your cycle did YOU experience implantation bleeding, what was it like, how long did it last and how long after did you get your period?
