This is my fourth pregnancy if i make it to term it will be 3rd baby. i think i am mistaking implantation bleeding for lmp. it was on 6/27 which was 8 days before af was expected. it started at night and seemed like it was gonna be heavy but by lunch the next day it was light and spotty by the end of 3rd day it was gone. what do you all think implantation bleeding or lmp? Thanks!
