Having a heavy period is 100% normal. But if you’re using 1+ pads an hour and feeling more tired than usual, something else might be going on…
When you first get your period, it’s natural to wonder, “Is my period normal?” And it’s only natural to look to our friends and peers to tell us if we’re “normal” or not. Maybe you’ve noticed you head to the bathroom to change pads more often than your friends. Or, you wonder if your friends worry as much about after-school sports leaks as you do.
But when it comes to menstrual cycles, the “normal” range is so big that your period patterns could be wholly unique to you and still healthy!
Here’s what can make this tricky: While a heavy flow can be completely normal, it is possible to have a flow that’s too heavy and is actually related to a different issue.
To help, here’s a quick guide to understanding your unique flow, what causes heavy periods, and 7 red flags you may want to seek medical support.
What Does a “Normal” Period Flow Look Like?
First things first — there’s a huge range of “normal” when it comes to your menstrual flow! Some of us naturally have lighter flows, while others experience heavy period bleeding. Both can be completely healthy.
On average, most people lose between 2-3 tablespoons of blood during their entire period. However, the CDC reports that it’s normal for people with heavier periods to lose up to twice this amount during their period.
Of course, it’s not like you’re measuring your period with a tablespoon! So, how can you know what type of flow you have? Over the next few sections, we’ll dig into how you can figure out your typical flow.
How many pads is it normal to use every day?
Experts recommend changing your pads every 3-4 hours to stay fresh and comfortable.
However, this can change depending on your flow:
- On an average, medium-flow day, you might use 4-6 pads.
- On heavier days or more active days, you might use 1-2 more pads.
- On less active low-flow days, you might use 1-2 fewer pads.
The good news: With more absorbent overnight pads, you’re usually good to go with one pad for the whole night.
Pro tip: Keep a few extra pads in your backpack or locker with Pinkie’s Prep Pouch! That way, you’re always prepared, no matter when your period surprises you or if your flow is heavier than expected.
Tips to Identify Your Flow Type
Understanding your flow can help you feel more confident and prepared during your period. Plus, it’s helpful information to share with your doctor if you ever have concerns! Here are some practical ways to understand your unique flow pattern:
Signs of a Light Flow
- You only need 3-4 pad changes the first couple of days
- You only need 1-2 pads the last days of your period
- You don’t usually need to wear an overnight pad
- You rarely notice any clots
Signs of a Medium Flow
- You change your pad 4-5 times the first two days
- You need 2-3 pads the last days of your period
- You notice spotting on overnight pads the first few days but don’t need them the final days of your period
- You have occasional clots smaller than a quarter
Signs of a Heavy (But Healthy) Flow
- You need to change pads 6-7 times the first few days
- You go through 3-4 pads a day towards the end of your period
- You need to wear overnight pads every night (or deal with laundry in the AM)
- You notice clots bigger than a quarter but smaller than a grape
Tracking Tips to Figure Out Your Flow
The best way to learn more about your “normal” flow is to take notes! Keep in mind that your period may be more irregular over the first two years, so it’s best to look for patterns over time.
Keep a period diary (either paper or digital) noting:
- How often you change your pad
- The heaviness of bleeding when you change (was the pad completely soaked?)
- Any clots you notice and their size
- Energy levels and other symptoms
- Activity level each day (sports, quiet days, etc.)
- Activities or habits that seem to change your flow
- Record symptoms you’re worried about so you can share them with your doctor
7 Red Flags Your Heavy Period Might Be Too Heavy
Abnormally heavy period flows are typically diagnosed as a condition called “menorrhagia.” Unlike healthy heavy flows, the body loses more blood than it should with menorrhagia. The blood loss can significantly drop iron levels and prompt many symptoms like fatigue, dizziness, and more.
7 signs of menorrhagia to look out for:
- You bleed for more than 7 days straight
- You’re soaking through your pad or tampon every hour
- You need to wake up during the night to change pads
- You spot blood clots that are bigger than a quarter
- You feel dizzy, short of breath, or unusually tired
- You find your period regularly interferes with school, sports, or daily activities
- You experience constant pain in your lower abdomen during periods
Remember: If you use more than 8 pads daily or soak through them hourly, please talk to your doctor. While it might feel scary, there are many ways to deal with menorrhagia! The first step is reaching out for help.
What Can Cause Abnormally Heavy Periods?
In the first couple of years, most heavy periods are simply your body figuring things out as your hormones regulate. About one-third of women eventually talk to their doctor about heavy periods, so you’re not alone if you’re concerned!
But if your period is too heavy, these are 4 common culprits that could be causing heavy bleeding behind the scenes:
- Hormone-Related Conditions
- PCOS (Polycystic Ovary Syndrome) can create hormone imbalances
- An underactive thyroid (hypothyroidism) can make periods heavier
- These conditions can make the lining of the uterus thicker than usual, leading to heavy menstrual bleeding
- Reproductive Health Conditions
- Non-cancerous growths called fibroids or polyps can develop in the uterus
- Endometriosis, where uterine tissue grows outside the uterus
- Adenomyosis, where uterine tissue grows into the uterine wall
- Birth Control Methods
- Some intrauterine devices (IUDs) might cause heavier periods, especially in the first year
- Changing birth control methods can temporarily affect flow
- Bleeding Disorders
- About 1% of people who menstruate have inherited conditions like Von Willebrand disease
- These conditions affect how well your blood clots
- Often discovered during teen years when periods start
The good news? All of these causes are manageable with proper medical care. Many people go on to live perfectly healthy, happy lives once they’re diagnosed and treated. The key is speaking up when you notice something doesn’t feel right.
