Your Menstrual Cycle Is Trying to Tell You Something — Are You Listening?

Most Women Know Their Period. Fewer Know Their Cycle.

There’s a difference. Your period is the 4–6 days of bleeding. Your cycle is the entire 28 (or 24, or 35) day process of hormonal events that either leads to pregnancy or resets for the next round.

If you’re trying to conceive, understanding your full cycle — not just when your period comes — is one of the most practical things you can do. And if something in your cycle isn’t right, it’s often the first clue that something needs attention.

A Quick Tour of the Four Phases

Phase 1: Menstruation (Days 1–5)

Day 1 of your period is Day 1 of your cycle. The uterine lining sheds. Meanwhile, the pituitary gland is already sending FSH to start recruiting follicles for this month’s potential egg.

Phase 2: Follicular Phase (Days 1–13)

Several follicles begin to grow. One becomes dominant and produces increasing amounts of oestrogen, which thickens the uterine lining and prepares the body for potential pregnancy. By Day 12–13, oestrogen peaks.

Phase 3: Ovulation (Around Day 14)

The oestrogen peak triggers a LH surge — and about 36 hours later, the dominant follicle releases its egg. This is your fertile window. The egg lives for only 12–24 hours. Sperm, however, can survive up to 5 days inside the reproductive tract — which is why the 3–4 days before ovulation are just as important as the day itself.

Phase 4: Luteal Phase (Days 15–28)

The empty follicle becomes the corpus luteum and produces progesterone. This prepares the uterine lining for implantation. If no pregnancy occurs, progesterone drops and your period starts.

How to Actually Track Ovulation

I get asked this constantly in clinic. Here’s what actually works:

• LH ovulation predictor kits (OPKs): Available at any chemist. Test from Day 10 onwards. A positive means ovulation is 24–36 hours away. This is the most reliable at-home method.
• Cervical mucus: Around ovulation, discharge becomes clear, stretchy, and slippery — like raw egg white. This is your body’s natural signal.
• Basal body temperature (BBT): Your temperature rises very slightly (about 0.2°C) after ovulation. Track it daily first thing in the morning. It confirms ovulation happened but doesn’t predict it in advance.
• Ultrasound monitoring: The most accurate method — we do this in clinic when we’re doing ovulation induction. We can see the follicle grow and confirm rupture.

What Irregular Cycles Actually Mean

If your cycle varies wildly — sometimes 25 days, sometimes 40 — that usually means irregular or absent ovulation. You can’t reliably time intercourse, and some months there may simply be no egg to fertilise.

In my experience, PCOS is the most common cause in younger women. Thyroid disease is the second most common. Both are completely treatable.

A transvaginal ultrasound on Day 2–3 of your cycle and a progesterone test on Day 21 can tell us a huge amount about your ovulatory health in just two tests.
