what it’s ACTUALLY like to be on your period // period week in my life

While its true that you can sometimes randomly miss a period for reasons like stress, you shouldnt just ignore a long-term missing period. Missing at least three menstrual cycles in a row qualifies as amenorrhea, the Mayo Clinic explains, and its usually very much worth bringing up to your doctor.

If your period randomly disappears and you have even the smallest chance of being pregnant, first and foremost, you should find out if you are, Alyssa Dweck, M.D., a gynecologist in Westchester, New York, and assistant clinical professor of obstetrics and gynecology at Mount Sinai School of Medicine, tells SELF. Sometimes people miss the obvious, she notes.

If youre not pregnant, talking to a doctor can help you make sure theres not another health issue going on, like PCOS. . Here are a few other things that could be making you miss your period:

Signs And Symptoms Of Heavy Periods:

Diagnosing heavy periods isnt always easy and women can often have the odd heavy one and then return to normal again. Below we outline some signs to look out for. If these are occurring more often than not, then it might suggest that your periods are heavy.

How much blood you lose:

The amount of blood loss per period is the obvious indicator of how heavy your period is. Periods are considered heavy if you lose more than 60 80ml per period . However, unless you have a tablespoon handy this might be hard to measure. Generally, if you are having to change your pad or tampon every hour for several consecutive hours then this is classed as a heavy period.


Flooding is a heavy surge of blood loss that often results in you soaking through your period product and onto your clothes or bedding. This shouldnt happen for an extended period of time or you can become anaemic very quickly. Frequent flooding suggests you have heavy periods.

Note make sure you are choosing the right period products for you. If the shape or size is wrong, you could leak as a consequence and confuse this for flooding.

Changing your period product during the night:

Generally having to get up during the night to change your period products can suggest you have a heavy flow.

During the night gravity means blood loss should be even slower, although flooding is more likely to occur when you stand up after a nights sleep if your periods are particularly heavy.

Blood clots:

Length of your period:

Does A Heavy Period Mean You Are More Fertile

There doesnt appear to be any link between the heaviness of your periods and your fertility level. However, many underlying causes of heavy bleeding can lead to an inability to get pregnant: issues like a hormone imbalance, uterine polyps or fibroids, endometriosis or pelvic inflammatory disease, so the reverse is actually more likely to be true. If you have any other symptoms besides a heavy period, it may be worth asking for further investigation if you are concerned.

  • Soaking through one or more sanitary pads or tampons every hour for several consecutive hours
  • Needing to use double sanitary protection to control your menstrual flow

Why Period Leaks Are More Common At Night

Theres definitely an art to stopping period leaks at night, and heres why:

When youre asleep, naturally, youre not checking and changing your period products as often. Usually throughout the day, youd be able to put a stop to any leaks before they happen, but this is impossible when youre catching some ZZZs.

Its easier to avoid leaks in the day time because gravity does its job and catches period blood on your pad, tampon or whatever products youre using. But when youre asleep, blood can fall to the side or at least not where you want it to fall, causing leaks.

This, combined with shuffling around from one position to another when youre sleeping, means your pants are likely to move or bunch, which is a recipe for disaster if youre trying to prevent period leaks.

SAGE Open Medicine , uterine polyps often have no symptoms. However, they can cause health issues, such as heavy bleeding and infertility.

Why Is My Period Heavier At Night

Why do you need extra protection against period leaks at night? The obvious reason is that youve been sleeping for several hours, which is longer than you would ordinarily go without changing your pad or tampon. Furthermore, blood flows differently while youre lying down than when youre upright.

Gravity will cause your menstrual fluid to fall to one side of your underpants if you lie down for several hours. Additionally, if you move around a lot while sleeping, your knickers may bunch up and leak. This is where leak proof period panties such as Kotex comes to the rescue. These period panties have a broader front and back for maximum comfort and protection throughout the night. However, we all know that periods can come at inopportune times, and nighttime leaks are the last thing on your mind.

You Bleed Through A Pad Or Tampon In An Hour Or Less Your Period Lasts Longer Than Seven Days Or Both

The medical term for an exceedingly heavy or long period is menorrhagia. Menorrhagia affects more than 10 million American women each year, or about one in five, according to the Centers for Disease Control and Prevention .

These are basically periods that would fit right into a scary movie, but some people dont even realize this kind of bleeding isnt normal. One of the biggest problems is someone being so used to heavy bleeding that she underplays the amount, Lauren Streicher, M.D., an associate professor of clinical obstetrics and gynecology at Northwestern University Feinberg School of Medicine, tells SELF. Shell come in and say her periods arent too bad, then say she has to change her tampon every hour.

One huge sign you may be dealing with menorrhagia: Passing period clots larger than a quarter, according to the CDC. While thats technically a good sign that your bodys clotting mechanism is trying to prevent you from losing too much blood, it also indicates that youre still passing much more blood than you should, as SELF previously reported. Even if your clots arent that big, soaking through a tampon or pad in an hour or less is a tip-off that your bleeding is too heavy and intense. Bleeding for more than seven days is another period problem that points at menorrhagia, the CDC notes.

Uterine fibroids are small, non-cancerous growths inside the uterus. And while they may sound scary, theyre actually much more common than youd think. One study from the Birmingham Womens Hospital found that 70 percent of women will have at least one before the time they reach 50and one of the main symptoms of uterine fibroids is heavy bleeding, sometimes with blood clots or bleeding in between periods.

According to the Polycystic Ovarian Syndrome Foundation, up to 10 percent of women have PCOS and approximately 50 percent of those women dont even realize they have it. Women with PCOS can get a cluster of cysts on their ovaries that could lead to heavier periods. According to Wysocki, ovulation, which is irregular for women with PCOS, triggers the conditions for the lining of the uterus to shed. If that trigger is absent, the uterine lining continues to thicken and later causes much bloodier periods.
