13dpo.....Is it too late for Implantation to occur?

Clarissa

Hi ladies, im currently 13dpo, AF is due to arrive tomorrow. With my earlier post i reported having sore boobs jus a few days after ovulation up until now. Today i noticed some brownish pink discharge after wiping. I had this awful lower bak pain amd felylt sick to my tummy as i usualy do wen i know my periods are starting bt that was for lyk 30min n then stopped. Usually that pain last around 2 days till i wase into my periods.

Could this be implantation or just the start of my period.

Its been a few hours now and still not that heavy, just wen wiping. How soon after the bleeding can i test? Just so anxious
