Cycle Day 1: Что происходит? Ранний выкидыш или гормональный сбой? Детали и симптомы

So it looks like cycle day 1 ive never experienced a missed miscarriage or a chemical before ive had a miscarriage back in 2011 but that was at 13 weeks im assuming this was either left over hormones or a very early miscarriage at least i know whats happening now as i was 8days late and tests were showing both positive and negative
