I think i have menorrhagia. what types of tests are used to determine if i do have it and why?

Defined by symptoms: Menorrhagia is a condition defined by your menstrual bleeding pattern. Menorrhagia simply means that you bleed heavily, such as having to change your tampon/pad every 1-2 hours or more often on your heavy menstrual days. The evaluation for heavy bleeding involves checking for anemia, blood problems such as low platelets, thyroid and other hormone problems, and an exam of the uterus and ovaries.

US & Blood Tests: Menorrhagia/Heavy Menstrual Bleeding is any period bleeding that leads to soaking a pad/tampon more than every 2hrs, interferes w/ daily activities, or lasts >7days. There are many causes: fibroids, polyp, hormonal imbalance (TSH/Prog/Estr), adenomyosis, bleeding disorders and cancer. Get checked out. Taking progesterone (pills/IUD) can help to thin the uterine lining so you don't bleed as much.

Menorrhagia: Menorrhagia means heavy periods that recur each month. Also, that the blood loss interferes with your quality of lifeA normal period is a blood loss between 30 and 40 ml (six to eight teaspoonfuls) per month. Bleeding can last up to eight days but bleeding for five days is average. A heavy period is a blood loss of 80 ml or more. http://patient.info/health/heavy-periods-menorrhagia
