well i had it, i think it was two weeks after my AF was due. Its not much at all though and not painful. i just wiped twice to see faint watery pink on the tissue and wiped 2 more times to find some brown(mucusy) stuff, and that was it, it left as quick as it arrrived
Mine came day 9-10 dpo and I bled for nearly 24 hours then stopped. So 5 and 4 days before AF was due....I'm now on 19dpo!
i always thought implantation bleeding was like 12-24 hours after implantation, between 7-14 DPO??
