My period came about 3 days late. it started spotting the first 2 days then on the 3rd day it came when I was urinating in clots that are black and very big. the blood flows only when I have to urinate and spotting happens otherwise. I have been getting severe cramps for the 3 days so far and is very weak and tired. also, I thought I was pregnant last month because it was about 1 week late. thank you.
