So for the past two months my periods have been different. I usually get not too heavy periods, but they're not light either. Two months ago my period was lighter than usual and last month It was light and it only lasted 3 days. I'm confused as to why this happens? I used to think I was pregnant because I had the green veins on my breasts and a funny feeling in my lower abdomen but I haven't actually had intercourse, just fooled around so I knowim not but imconfused.
