UcenterDress light blue items to wear of the prom

I was wondering what reasons my period could be extremely light and short besides from being pregnant! This would be second period after baby...bled for a super long time pp. My first period after baby was late about a week and a little lighter than usual and I hadn't had sex so I know pregnancy had nothing to do with it. I am not on bc and currently just moved pretty stressed I'd say If that helps any. Thanks so much! UcenterDress light blue items to wear of the prom
