A change in your cycle is worth understanding
Periods do not have to arrive on exactly the same date every month. Some variation is common. What matters is noticing a change from your usual pattern and discussing changes that concern you. 4, 5
A late or missed period does not automatically mean PCOS. Stress, substantial weight changes, excessive exercise, hormonal contraception, pregnancy and thyroid conditions can also affect the cycle. Periods can be less predictable when they first begin and during the transition towards menopause. 4
What should I record?
A simple diary can help you describe the pattern clearly. Record the first day of each period, how long bleeding lasts and whether it seems different from usual. Note bleeding between periods, pain or other symptoms you want to discuss. You can use a notebook; an app is optional. 4, 5
For the appointment, you could bring a short list:
- The dates of your recent periods, if available.
- Your main concern and how it affects daily life.
- Medicines, contraception and supplements you use.
- Whether pregnancy is possible or you are planning a pregnancy.
- Previous test results or treatment records, if you have them.
You do not need a perfect record before seeking help. Start with what you remember and ask the doctor what else would be useful to track.
When should I arrange a consultation?
Discuss persistent irregularity, a change in your usual pattern, periods lasting longer than seven days or difficulty becoming pregnant with a clinician. Bleeding between periods or after sex should also be checked. 4, 5
Bleeding after menopause needs assessment even if it happens only once or is a small amount. There are several possible causes, and checking it helps identify the right next step. 6
What happens next?
Treatment depends on the cause, and irregular periods do not always require medication. Your clinician can decide whether investigations are needed and explain appropriate options. 4
The aim is to understand your pattern and concerns together. You can ask what a proposed test is looking for, how the result would affect treatment and when to follow up.
