I was like 8 days late on starting my period then i started on the 11th day it was heavy mostly it lasted for 4 days shorter than my usual periods but before I had the bleeding i was light headed vomiting for 1 day and dry heaving for 3 straight nights, very very fatigued. at first i spotted then next morning i had found i started very heavy. I figured i must have had a miscarriage or something. could i have been pregnant and then lost it by the amt of blood lost, maybe I am still if i was in the first place what do you think?
