It : It may be that your hormones are off balance, which can happen from conditions such as stress or weight changes (weight too high or too low). If there is any chance that you are pregnant please take a test (some pregnancies can cause spotting or bleeding). If you have pain, soaking more than a pad an hour, light-headedness, fainting or vomiting then you would have to be seen as an emergency.

There : There are a number of possible explanations for your early bleeding, including ovarian cysts, thyroid disease, obesity, endometriosis, and certain sexually transmitted diseases. Your other symptoms (swollen breasts, nausea, etc.) suggest there's something hormonal going on, such as an ovarian cyst or a thyroid problem. However, in many cases the cause of an early period can't be identified; these irregularities usually resolve, and within a cycle or two your normal pattern resumes. Given your urinary frequency, dizziness, and intestinal symptoms, it would be prudent to see your doctor for an evaluation. He/she may want to check your thyroid function and/or order a pelvic ultrasound to see if you have an ovarian cyst. If you're at risk for sexually transmitted diseases, further testing might be necessary. I've attached a link that provides more information about abnormal menstrual bleeding. I hope things settle down for you soon! http://www.Medicinenet.Com/vaginal_bleeding/page3.Htm.
