I'm having exssive bleeding when I flow.

Menorrhagia. is the term applied to heavy bleeding that occurs with a normally timed menstrual period (if frequent periods: metrorhaggia). Causes include hormonal imbalances, ovarian dysfunction, uterine fibroids or polyps, adenomyosis (uterine glands "invading" muscle), bleeding disorders, pregnancy complications, cancer. When to see doc: bleeding limiting lifestyle, possibly anemic, change tampon every 1-2 H.
