Understanding Common Menstrual Symptoms

Most women notice physical or emotional changes around their periods. For many they are mild; for some they disrupt work, school or sleep. Knowing which symptoms are common, what eases them and which ones are not normal helps you manage your cycle and seek help when needed.
Key points
- Cramps, bloating, breast tenderness, tiredness and mood changes are common before and during a period.
- Warmth, gentle exercise, sleep and over-the-counter pain relief help many people.
- Severe pain, very heavy bleeding or symptoms that interfere with daily life should be discussed with a doctor.
Period pain
Period pain is caused by the muscular wall of the uterus tightening to shed its lining. It is usually felt as cramps in the lower abdomen, which can spread to the back and thighs. It often starts when bleeding begins and lasts two to three days.
What can help
The NHS suggests:
- a heat pad or hot water bottle on the abdomen, or a warm bath or shower;
- gentle exercise such as walking, swimming or yoga;
- light massage of the lower abdomen;
- pain relief such as ibuprofen or acetaminophen, if suitable for you. Ask a pharmacist.
Self-warming patches, such as our Air-Activated Heat Patches, provide warmth under clothing. Do not apply them directly to the skin or use them while sleeping.
Premenstrual syndrome (PMS)
PMS is a group of symptoms that appear in the one to two weeks before a period and usually ease once bleeding starts. The Office on Women’s Health notes that most women have at least some symptoms.
Physical symptoms
- Swollen or tender breasts
- Bloating or a gassy feeling
- Cramping
- Headache or backache
- Constipation or diarrhea
- Tiredness
Emotional symptoms
- Irritability
- Mood swings
- Feeling anxious, tense or sad
- Sleeping too much or too little
- Appetite changes or food cravings
- Trouble concentrating
What can help
- Regular physical activity
- Balanced meals with less salt, sugar and caffeine around your period
- Enough sleep
- Stress-reducing activities
- Not smoking
A small number of women have a severe form called premenstrual dysphoric disorder (PMDD), with marked depression, irritability or anxiety before periods. It is treatable and should be discussed with a doctor.
Heavy bleeding
Flow varies between people. The NHS describes periods as heavy if you:
- need to change a pad or tampon every one to two hours, or empty a menstrual cup more often than recommended;
- need to use two types of product together;
- have periods lasting more than seven days;
- pass large blood clots;
- bleed through to your clothes or bedding;
- avoid daily activities or feel tired or short of breath a lot.
Heavy periods can cause iron-deficiency anemia and have many treatable causes. See a doctor if this describes your periods.
Other common symptoms
- Breast tenderness: often eases after the period starts. A supportive bra helps.
- Bloating: may improve with less salt and regular activity.
- Headaches: some women have migraines linked to their cycle.
- Acne flare-ups: related to hormone changes.
- Digestive changes: looser stools are common during a period.
- Tiredness: rest, and consider whether heavy bleeding might be causing low iron.
Tracking symptoms
Keeping a diary for two or three cycles shows whether symptoms follow a pattern. Record the days of bleeding, how heavy it is, pain levels and mood. This is valuable information for a doctor.
When to seek medical advice
See a doctor if:
- pain is severe, getting worse or not helped by pain relief;
- pain or other symptoms stop you from doing normal activities;
- your periods become heavier, more painful or irregular;
- you bleed between periods or after sex;
- premenstrual symptoms affect your relationships, work or mental health;
- you have symptoms of anemia, such as tiredness, breathlessness or pale skin.
Painful or heavy periods are sometimes caused by conditions such as endometriosis, fibroids or pelvic inflammatory disease, which can be treated.
Seek urgent help if
- you have sudden, severe pelvic pain;
- you are soaking through a pad or tampon every hour for several hours;
- you feel faint or dizzy with heavy bleeding;
- you develop a fever, rash or vomiting while using a tampon or cup.
Supplies that help
Keep suitable products ready for heavier and lighter days, for example Ultra-Thin Pads with Wings and Daily Cotton Liners.
