My supposed last period was December 7 2016 bht in October i miscarried,then i got my normal 28 day cycle period November the 10 2016 but when it actually came to December i was 6 days late which means i got my period December 12 2016 and it lasted about 8 days and i nomally only bleed for 4-6 days max,and since then i didn't get my periods...i am currently pregnant tho i really don't know how far,so can anyone explain to me if December was implantation bleeding or a supposed late period????!!!!
