I am having an unusuall period, everyone knows what their period is like towards the end of their "time" of the month, my period has started out that way, and I am just spotting, normally I am a heavy bleeder. Normally I get cramps really bad before my period and during my period, but I haven't at all. Normally I am craving food like crazy, and I have actually had a loss in appetite, I haven't wanted anything but fruit, and lots of strawberry and bananas, and I have been so exhausted. Normally I get tiered during this time of month, But I have never been this tired, should I be worried?
