A typical period involves a total blood loss of about 30 to 80 milliliters (roughly 2 to 5 tablespoons) over a duration of 2 to 7 days. What is considered "normal" can vary widely from person to person.
You may have heavy periods if you: need to change your pad or tampon every 1 to 2 hours, or empty your menstrual cup more often than is recommended.
The first day of a woman's period is day 1 of the menstrual cycle. Periods last around 2 to 7 days, and women lose about 20 to 90ml (about 1 to 5 tablespoons) of blood in a period. Some women bleed more heavily than this, but help is available if heavy periods are a problem.
Signs of heavy menstrual bleeding include: Periods lasting longer than seven days. Passing blood clots that are the size of a quarter or bigger more than once or twice. The blood may appear red, pink, brown or even rust-like.
The average total amount of blood lost during a period is 35ml. Bleeding is considered abnormal when more than 80ml is lost, because if you are losing more than 80 ml during each period, you are at a risk of developing anaemia. Some women lose much more blood.
Periods that last for more than 7 days are considered heavy. Periods that require a new tampon or pad after less than 2 hours or involve passing large clots are considered heavy. Your healthcare provider can determine if you might need testing for a possible bleeding disorder. Treatments are available.
“You may have really small clots that might be a dime-size or a quarter-size during your period and that's normal for you,” she says. “It's problematic if you're passing golf ball-sized clots and passing them every couple of hours.” You should also be concerned if you must change your pad or tampon about every hour.
Heavy bleeding is not normal and may need treatment if:
→ Heavy periods (typically first 2 days): Change pad every 3-4 hours. May use up to 6 pads per day.
A stress period looks like menstrual changes due to hormonal disruption, featuring spotting, early/late/missed periods, heavier/lighter flow, longer duration, bigger clots, more cramping, worse PMS, and potential loss of libido, alongside physical signs like headaches, fatigue, muscle tension (neck/back pain), jaw clenching, and digestive issues, all stemming from elevated cortisol and disrupted reproductive hormones.
Your periods become irregular after having been regular. You bleed for more than seven days. You bleed more heavily than usual or soak through more than one pad or tampon every hour or two. Your periods are less than 21 days or more than 35 days apart.

Causes of weight gain before and after the menstrual cycle
Due to changes in progesterone and estrogen hormones at this time, the body has many fluctuations. Up to 90% of women experience this weight gain because hormonal changes in the body cause the tissues to retain more water, causing water heaviness.
Your period can last between 2 and 7 days, but it will usually last for about 5 days. The bleeding tends to be heaviest in the first 2 days. When your period is at its heaviest, the blood will be red. On lighter days, it may be pink or brown.
Menorrhagia red flags include soaking pads/tampons hourly for hours, needing double protection (pad + tampon), changing products overnight, passing clots bigger than a quarter/50-cent coin, bleeding over 7-8 days, extreme fatigue/shortness of breath (anemia signs), limiting activities due to flow, or pain/pressure/masses, indicating you need to see a doctor for potential causes like fibroids, polyps, hormonal issues, or bleeding disorders.
Home remedies-
If you have to change your pad or tampon less than every 1 to 2 hours because it's soaked, bleed longer than 7 days, or you pass clots the size of a quarter or larger see your healthcare provider. Spotting or bleeding between periods is also a sign of a problem.
Heavy menstrual bleeding may be a sign of an underlying health problem that needs treatment. Blood loss from heavy periods also can lead to a condition called iron-deficiency anemia. Severe anemia can cause shortness of breath and increase the risk of heart problems.
Check regularly when you go to the bathroom. You might notice a feeling of wetness or dampness, occurrence of stains or the pad may feel heavy in your undies. These are all signs that the pad may be full. In this case, switch to a clean pad.
Period pain red flags include pain so severe it stops you from daily activities (work, school), doesn't improve with OTC meds (ibuprofen, Panadol), involves very heavy bleeding (soak pad/tampon hourly), or comes with new symptoms like painful sex, fatigue, digestive issues, or fever, signaling potential conditions like endometriosis, fibroids, or adenomyosis needing medical attention.
Women start perimenopause at different ages. You may notice signs, such as your periods becoming irregular, sometime in your 40s. But some women notice changes as early as their 30s or as late as their 50s.
Endometriosis-related blood clots often look like dark red or brownish, thick, jelly-like, or even liver-textured clumps, sometimes containing fleshy tissue fragments, and are larger than a quarter (grape or golf ball size), occurring with heavy flow that saturates pads quickly. While normal clots are usually small, significant clotting, especially with severe pain or heavy bleeding, signals a need for medical attention to check for conditions like endometriosis or adenomyosis, notes this article from the Center for Endometriosis Care.
The following list outlines symptoms that might suggest you're losing more blood than expected (5,6,8): Your menstrual bleeding lasts for more than eight days. You soak through your tampons or pads every one to two hours. You use more than one pad at a time to manage your menstrual flow.
You might observe that as you age, your period pain can change. For some, period pain is common in the early years after their first period but tends to improve with time. However, for others, it's like period pain getting worse with age, especially as they reach their 30s and 40s.
