I had it about 5 days after I was supposed to get my period, but I only had it with my first child. The other 2 I never spotted with.
they say implation occurs between 6-12 dpo..
looking back now i fell like i felt implantation arouned 7 or 8 dpo because i was feelig litle oains assuming AF was gonna show early possibly
with ELi i felt it at 7dpo,
with annabelle i felt it at 5dpo had a bfp at 8 dpo
ive never had implantation bleeding.. with all my prengancies
Good luck momma :)
