hormones out of control !!!

this week I've not been feeling myself at all.. my hormones are out of control and I can barely contain my emotions ,weeping at everything ... not pregnant , not pmsing as I just finished my period 4 days ago.. I just don't know what s going on..do I go to the Dr? and if so do I see my regular Dr or my gyno? .. I just can't help crying, and feeling so sensitive.. things are good in my life, my job etc so nothing bad is going on .. any help is appreciated
