Gina, sweetie...love of m life
Get thee to your doc for a blood test first to find out about your vitamin levels. Your iron levels can certainly effect your periods. I would also see a gyno about the menopause thing just in case. Have you started or been taking any form of birth control? That could also cause different periods. Now I know you're on a break since you teach, so I know you have the time to make a doctors appointment...go do it darlin'!!!
