So my last period was on september 19th 2018 and i finished on the 25th which i was late a week, i started on my cycle day 44th! I usually last 6 to 7 days! With AF. I was suppost to start around the 20's in october so im like on cycle 47 and no period but i actually did bleed on the 31st halloween night but it was just once when i wiped and it was bright red like my period but thats it i havent had any more AF! Could it have been implantation? Or did i only have AF for not even a day! ?
