But some research suggests that this figure may actually be closer to 60 milliliters, or about 4 tablespoons. If you want to figure out where you fall on the menstrual spectrum, read on. You expel more than just blood during menstruation. Your menstrual fluid also contains a mix of mucus and uterine tissues, which can add volume to your overall fluid loss. The hygiene products you use can help you get a rough estimate of your overall flow.
And if you want an accurate account of pure blood loss, math is on your side. One of the easiest ways to measure fluid loss is with a menstrual cup. Some cups even include volume markings for easy reading. Depending on the brand and type, your menstrual cups may hold anywhere from 30 to 60 milliliters at a time. You can record this as a note in your phone or keep a log. Then empty, wash, and reinsert as usual.
Continue to update your log for your next three or four periods. This should give you enough data to determine your average menstrual loss per day and per week. You may find that your entire period loss is greater than 60 milliliters. Regular tampons, for example, hold 5 milliliters of fluid. Super tampons hold double that. If you lose 60 milliliters during your period, you may soak through 6 to 12 tampons depending on the size you use. Logging this info for your next three or four periods will give you enough data to calculate a reasonable estimate.
If you can help it, avoid fully soaking an absorbent product. The amount, length, and frequency of periods around the time of menarche can vary greatly. As you progress through adolescence, period amounts and cycles become more regular, but may still be somewhat variable 2, Adolescent periods can also be up to 80 mL per period, like the adult range, but are often lighter 2.
Hormonal birth control HBC options like the pill, vaginal ring, or patch control the release and regulation of hormones like estrogen and progesterone within your body. When used correctly, the hormones in HBC prevent your ovaries from preparing and releasing eggs ovulation.
Your period will change depending on the type of HBC you use. The bleeding you experience while using hormonal birth control is called withdrawal bleeding , and is not considered a menstrual period. Withdrawal bleeding is caused by the decline in reproductive hormones in your body during days when you get low or no hormones from your pill, patch, or ring 10, When affected by hormonal birth control, the lining of your uterus doesn't thicken as much as it does without hormonal birth control.
There are many different types of hormonal birth control, all containing differing types and levels of hormones. Some types of birth control do not contain any estrogens and only contain progestin—a synthetic form of progesterone These methods include progestin-only pills the mini pill , progestin injections the shot , or progestin implants When using progestin-only birth control pills, you may not have a typical menstrual cycle.
Some progestin-only pills suppress ovulation, but it depends on the type Bleeding can vary a lot on progestin-only contraceptives. Changes in period amount happen in response to the changes in hormones. These hormones affect the growing and shedding of your uterine lining. Many people experience irregular bleeding, reduced bleeding, shorter cycles, or amenorrhea no menstrual period with progestin-only pills, especially when pills are not taken at the same time every day Methods like the contraceptive injection and the implant suppress ovulation 16, But there are several conditions and some treatments that can cause heavy menstrual bleeding.
Some conditions of the womb and ovaries can cause heavy bleeding, including:. A GP will start by asking you about your heavy bleeding, any changes to your periods and any other symptoms you have, like bleeding between your periods or period pain.
All women who have heavy periods should be offered a blood test to check for iron deficiency anaemia. The GP may also suggest a physical examination or refer you for further tests to try to find out if there's an underlying cause for your heavy periods.
