Missing periods, now light spotting and it's not time for my period
I missed my period for the last two months. I was nervous when I missed the first one so I was taking pregnancy tests and they were all coming back negative, the second month came and no period so I still had the thought that I may be pregnant, even some of the symptoms, but still negative results, today I started having some light spotting, but its not time for my period. What would cause this to happen? Is it possible that I'm getting ready to start my period? PLEASE HELP!
