I have been very moody for the past month my breasts were sore for about two weeks straight. My period was on time but itlasted only for about a day and a half. The first day it was very sticky bright red the next day it was not heavy also sticky texture. So on day 3 I was waiting for a heavier period but nothing it was just very light spotting. And today sept 24 I only had brown spotting for about 3 hrs now its gone. What could this mean? I have un protected sex with my husband could this mean I am pregnant? Worried!
