Should I be concerned?

Kristi
Ever since this past weekend I have been very emotional and not my happy perky self. I had a crying episode for no reason (I really have no idea why I was crying) this past Saturday and again last night? No reason again. I don't know if I'm super sensitive, if I'm depressed or what? I mean I'm getting my period in a week but I've never had these emotions around my period before and I don't think I'm pregnant. I love my job family and am head over heels for my fiancé! Please if anyone could give me some insight I'd greatly appreciate becUse in getting a little worried
