No period for 3 months or more, when you are not pregnant, is a reason to see a doctor soon. In PCOD the egg often does not release, so periods can stop for months. A doctor can give a simple treatment that protects the womb lining.
A late period is annoying. A period that does not come for months can be frightening. In PCOD it is common, and there is a simple reason for it.
What counts as a missed period
A typical cycle is every 21 to 35 days. Gaps longer than 35 days are worth checking. The usual line for "missed" is no period for 3 months or more, when you are not pregnant.
If this has happened, the first step is a pregnancy test. If it is negative and your period still does not come, book a doctor's visit. This does not need to wait for the next gap.
Why PCOD causes missed periods
Each month, a follicle in the ovary normally grows and releases an egg. After the egg is released, progesterone rises and prepares the womb lining. If there is no pregnancy, the lining sheds and a period starts.
In PCOD the egg often does not release. Without ovulation there is no progesterone rise, so periods become late, missed or heavy. High insulin and high androgens disturb the cycle too. That is why a period can slip by for months and then arrive heavy.
Other reasons for a missed period
PCOD is not the only cause. Thyroid and prolactin problems can look like PCOD, which is why doctors always test for them. Stress hormones affect insulin and ovulation, so a hard stretch can pause the cycle. Pregnancy is the other obvious cause, and the one to rule out first.
The point is that a missed period is a message from your hormones, not a verdict. A doctor works out which message it is.
Why skipped periods matter
If periods are missed for many months, the womb lining can keep thickening. Over the years this can cause heavy bleeding and, rarely, serious lining changes.
This is not meant to scare you. It is the reason to act early. A doctor can give a simple treatment to protect the lining. Aim for a period at least every 3 months, and tell your doctor if that is not happening.
What a doctor may do
Your doctor may advise a pelvic ultrasound, which can show how thick the lining is. Blood tests may include LH, FSH, AMH, prolactin and TSH. A lining biopsy or a hysteroscopy is done only if needed.
To protect the lining, options include cyclic progestin, a progestin-releasing IUD or hormonal pills. If you want a baby, the plan is different, and ovulation medicines may be the first step. Your doctor chooses what suits your goal, and you should take medicines only on that advice.
What you can do yourself
Keep a record. Write the first day of every period, the number of days, flow and any pain. Bring it to your appointment.
Look after the basics too. Food, movement, sleep and stress all affect ovulation. If you carry extra weight, losing 5 to 10% of your body weight can bring back regular ovulation and periods. Start with one small habit this week, such as a 10-minute walk after meals.
Questions to ask your doctor
- Why are my periods not coming, and what else needs ruling out?
- Which tests do I need, and how often?
- Does my womb lining need protecting, and how?
- What are my goals for the next 3 months?
- If I want a baby, when should I plan it?
Write the answers down, or ask for them in writing. It is easy to forget half of what was said once you are back in the corridor.
Teenagers
Irregular periods are common in the first 2 to 3 years after the first period. A doctor can check whether it is simply the body settling in. See a doctor if there is no period by age 15, or more than 3 years after breast growth began.
