What are the 4 phases of the menstrual cycle?

The menstrual cycle consists of four phases: menstruation, the follicular phase, ovulation, and the luteal phase. Knowing your menstrual cycle will enable you to estimate when you will probably become pregnant. Speak with your doctor if your menstruation causes you concern.

Is it possible to get pregnant in the luteal phase?

Conception occurs in the luteal phase. However, the most fertile days of your cycle, your best chances to get pregnant, occur in the follicular phase. If you try to get pregnant waiting until AFTER ovulation, you only have 12 to 24 hours for conception to take place.

Does your face change during the luteal phase?

According to certain research, your face's texture and form could change in the luteal phase. Studies suggest that changes could include your nose being larger, your eyebrows getting more noticeable, and the lower half of your face getting bigger.

Luteal vs Follicular Phase: Hormonal Changes, Symptoms & Cycle Support

Your menstrual cycle isn’t just about your period. It’s a monthly rhythm with distinct phases, and each one affects how you feel, think, and even function. The two key phases you might hear about the most are the follicular and luteal phases. They may sound technical, but once you understand the difference, you’ll notice how much your body changes across the month.

What Is The Luteal Phase?

The luteal phase is the second part of your monthly cycle. It starts just after ovulation and continues until your period starts. Your body moves into a "just in case" state during this period, ready for a potential pregnancy. The follicle from the released egg creates a transient hormone-producing tissue known as the corpus luteum, which releases progesterone.

Progesterone can affect your mood, energy, and even desires and thicken your uterine lining. If fertilisation fails, hormone levels decline, and your period starts, therefore ending the luteal phase.

Duration: Usually 10–14 days, and tends to be fairly consistent month to month.

What Is The Follicular Phase?

The follicular phase marks half of your cycle. It begins on the first day of your period and finishes during ovulation. This is your body preparing to release an egg. Hormones such as oestrogen and follicle-stimulating hormone (FSH) are really important here. Oestrogen increases slowly, strengthening the uterine lining and increasing energy and mood.

Often referred to as the "rising" phase, this one is your body gearing up, and you can feel more physically active, determined, and focused.

Duration: Typically 10–16 days, and may vary more than the luteal phase.

How You Feel During Each Phase

Your body changes physically in the follicular and luteal stages, but your energy, mood, and even perspective change as well. Once you understand these patterns, you can work with your cycle instead of against it.

Fertility Awareness

Follicular Phase: Beginning shortly after your period, this phase drives increased ovulation. This is your most fertile window. If you are attempting to conceive, this is the time to focus on cervical mucus, energy levels, and physiological signs, including higher desire. You can naturally match intimacy with your ovulation window by monitoring these signals.

Luteal Phase: This phase begins after ovulation. If conception occurs, your body begins to get ready to sustain a possible pregnancy right away. Your basal body temperature stays high. You may experience mood swings, bloating, or breast discomfort. If you are monitoring for pregnancy, this is the time to start the dreaded "two-week wait" before tests. It's also a wonderful time to calm down, take care of yourself, and stay mindful of your body's early signs.

Energy levels

Follicular Phase: Usually, this is the phase in which your energy picks up. Particularly following the end of your period. Rising oestrogen provides that lift. You might be more driven to start initiatives, work out, or agree to social plans. This is a wonderful time for cardio exercises, experimenting, or organising big tasks.

Luteal Phase: After ovulation, progesterone rises, making you feel a little slower, sleepier, or even drained. If you're feeling more tired or less driven, it's not in your head. You might find yourself reaching for rest more often, and that’s perfectly normal. Like walking or stretching, gentle movement usually feels better here than high-intensity workouts.

Mood

Follicular Phase: Oestrogen boosts energy and is linked to better mood and mental clarity. You may feel more optimistic, focused, and sociable. This can be a great time for brainstorming, networking, or having important conversations.

Luteal Phase: As progesterone takes over, your mood might dip. You could feel more sensitive, anxious, or irritable, especially in the days right before your period. This is when PMS tends to show up. Knowing this can help you give yourself more grace, and maybe say no to extra stress when possible.

Cravings and Appetite

Follicular Phase: Appetite tends to be lower here. You might notice fewer cravings, especially for sugary or heavy foods. This is partly because oestrogen has an appetite-suppressing effect.

Luteal Phase: Here comes the cravings, especially for carbs and sweets. Your metabolism speeds up slightly, and your body wants more energy. Don’t be surprised if you are hungry more often or reaching for comfort food. It's not about "willpower", it’s biology. Just aim for balanced choices when you can.

Productivity & Focus

Follicular Phase: You’re generally more focused and productive here. Mental clarity is sharper, and problem-solving feels easier. It’s a great time to start new projects or get through to-do lists that require energy and structure.

Luteal Phase: You might find it harder to concentrate for long stretches or feel a bit more distracted. That’s okay. This phase is actually ideal for reviewing, editing, tying up loose ends, and checking in on your emotions. Think of it as a time for reflection rather than initiation.

Why This Matters

Once you start tracking your cycle and noticing these shifts, you can plan life around your biology, whether work, workouts, social commitments, or even family planning. Understanding your follicular and luteal phases can help you identify your most fertile window, optimise your chances of conception, and better support early pregnancy. It’s about syncing with your natural flow, not working against it.

You don’t have to change everything overnight. Just start noticing the pattern. With time, you’ll learn what your body needs in each phase and that awareness alone can make a huge difference.

Want to get even more in sync? Try tracking your cycle for a couple of months and jot down how you feel physically, emotionally, and mentally during each phase. You’ll be surprised how much your body’s been trying to tell you.
