Dysmenorrhea: If this happen on and off you may be suffering from dysmenorrhea. It won't hurt to have a ob-gyn check because in many cases there is an effective treatment.

Anxiety: Nausea ; ibs can be caused by anxiety. Enroll in a course on life coping skills. If you are having an unusual period it is nothing to worry about. It is for some a very common event. It is also common to start and stop a day and resume. Feelings of being unable to move are also an over reaction to life's events to include monthly periods or nausea. Take tums (calcium carbonate).
