Where Do You Bleed From On Your Period

What Happens During The Menstrual Cycle

How to deal with period pain | NHS

In the first half of the menstrual cycle, your levels of estrogen rise and make the lining of the uterus grow and thicken. In response to the follicle-stimulating hormone, an egg in one of the ovaries starts to mature. At about day 14 of your cycle, in response to a surge of luteinizing hormone, the egg leaves the ovary. This is called ovulation.

In the second half of the menstrual cycle, the egg begins to travel through the fallopian tube to the uterus. Progesterone levels rise and help prepare the uterine lining for pregnancy. If the egg becomes fertilized by a sperm cell and attaches itself to the uterine wall, you become pregnant. If the egg is not fertilized, it either dissolves or is absorbed into the body. If pregnancy does not occur, estrogen and progesterone levels drop and the thickened lining of the uterus is shed during the menstrual period.

During your menstrual period, the thickened uterine lining and extra blood are shed through the vaginal canal. A woman’s period may not be the same every month, and it may not be the same as other women’s periods. Periods can be light, moderate, or heavy, and the length of the period also varies. While most menstrual periods last from three to five days, anywhere from two to seven days is considered normal.

For the first few years after menstruation begins, periods may be very irregular. They may also become irregular in women approaching menopause. Sometimes birth control pills are prescribed to help with irregular periods.

What Is A Normal Amount Of Bleeding During My Period

The average woman loses about two to three tablespoons of blood during her period.8 Your periods may be lighter or heavier than the average amount. What is normal for you may not be the same for someone else. Also, the flow may be lighter or heavier from month to month.

Your periods may also change as you get older. Some women have heavy bleeding during perimenopause, the transition to menopause. Symptoms of heavy menstrual bleeding may include:

  • Bleeding through one or more pads or tampons every one to two hours
  • Passing blood clots larger than the size of quarters
  • Bleeding that often lasts longer than eight days

The Age A Girl Gets Her First Period

Menarche is another name for the beginning of menstruation. In the United States, the average age a girl starts menstruating is 12.However, this does not mean that all girls start at the same age. A girl can begin menstruating anytime between the ages of 8 and 16. Menstruation will not occur until all parts of a girl’s reproductive system have matured and are working together.

Types Of Bleeding Between Periods

There are a few different types of bleeding that can happen when you’re not on your period.

  • Spotting: A red or brown tinge on the toilet paper or a drop or two of blood in your underwear is likely to be spotting. However, your provider will only consider bleeding to be “spotting” if it’s not happening during your period and does not require you to use a pad or tampon.
  • Light bleeding: This type of bleeding occurs just before or after your period. It’s not technically spottingit’s considered part of your period.
  • Breakthrough bleeding: Breakthrough bleeding happens if you are taking oral contraceptives. This type of bleeding between periods is usually caused by low estrogen levels.
  • Abnormal bleeding: Any heavy bleeding that requires the use of a tampon or pad that happens outside of your cycle and is not caused by hormonal birth control pills is abnormal. It is also called abnormal uterine bleeding or abnormal vaginal bleeding.

The Answer Lies In The Details: Menstrual Blood Vs Menstrual Fluid

All you need to know about implantation bleeding

I couldnt get the 30 to 50 ml of blood loss on average, equations and pad-washing as means to get to this result out of my head. I had to check the Alkaline-Haematin-Method again and discovered that I had missed a crucial detail: What if the method is only considering the quantity of menstrual blood and not all of the menstrual fluid?

Those menstruating may have realized that what menstrual cups, pads or actually any menstrual product collect isn’t just blood. In some cases, blood only makes up 36% of the menstrual flow. Although some publications mention this to be around 50-60%, it still shows that the period flow is not as simple as a nosebleed.

So of course, the menstrual flow is made up of blood and other substances , the other substances being uterine lining and other tissue, no wonder a menstrual cup fills up faster and my experience is far from the 30-50 ml norm. Just imagine a small shot glass of water and adding pebbles. Its physics!

Going forward from this theory, I made a very basic calculation with the NHS number of 40 ml of average blood loss during a period and came to a result of 111 ml of total menstrual fluid lost during a period. Heres how I calculated that:

What Causes Vaginal Bleeding Between Periods

A lot of things can cause bleeding between periods, including changes to your hormone levels, using hormonal contraception and infections. It is also common for women to bleed slightly around 10 to 14 days after their period, when an egg is released from the ovary since this causes hormone levels to change. This is sometimes called ‘spotting’ because the bleeding is generally very light. If you notice bleeding between your periods more than once or twice, you should speak to your doctor to check if this needs to be investigated.

General Overview Of The Menstrual Cycle:

The menstrual cycle includes several phases. The exact timing of the phases of the cycle is a little bit different for every woman and can change over time.

Cycle days

The first day of menstrual bleeding is considered Day 1 of the cycle.

Your period can last anywhere from 3 to 8 days, but 5 days is average.

Bleeding is usually heaviest on the first 2 days.

Days 6-14

Once the bleeding stops, the uterine lining begins to prepare for the possibility of a pregnancy.

The uterine lining becomes thicker and enriched in blood and nutrients.

Day 14-25

Somewhere around day 14, an egg is released from one of the ovaries and begins its journey down the fallopian tubes to the uterus.

If sperm are present in the fallopian tube at this time, fertilization can occur.

In this case the fertilized egg will travel to the uterus and attempt to implant in the uterine wall.

Days 25-28

If the egg was not fertilized or implantation does not occur, hormonal changes signal the uterus to prepare to shed its lining, and the egg breaks down and is shed along with lining.

The cycle begins again on Day 1 menstrual bleeding.

Tears Can Result From Dryness Or Birth Control Pills

Tears can happen around the opening of the vagina or deeper inside, Millheiser told INSIDER. Most occur as the result of dryness and vigorous sex. That said, women on the pill may be more prone to tears because birth control can cause the tissue of the vagina to be thinner, according to Millheiser.

Small tears that bleed for a few minutes after sex are common, but Millheiser said more serious tears could require an emergency room visit and stitches.

Millheiser also told INSIDER that the rate of blood flow and the amount of blood can help you distinguish between your period and a tear. “If you’re bleeding bright red blood profusely after sex, there’s likely something else going on,” she said.
