Follicular phase

# Sadness in the follicular phase: why it happens

Sadness in the follicular phase is less common than premenstrual sadness, but it can happen while estrogen and progesterone are both still low in the days after your period. Cortisol also runs higher here than in the luteal phase, which can read as edginess for some. Track a couple of cycles to see if the pattern holds.

Follicular phase

Days 1 to 13

Where this sits in your cycle - Period - Building - Ovulation - Luteal - PMS window

## At a glance

- Estrogen and progesterone are both near their lowest point right after your period, before estrogen climbs toward ovulation.
- Cortisol runs higher in the follicular phase than the luteal phase on average (Hedges' g = 0.13, meta-analysis of 778 women, Frontiers in Endocrinology, 2020).
- Most cycle research finds the lowest mood in the week before the period, not after it, so follicular sadness is a less typical pattern.
- In women with a PMDD-like mood pattern, higher mid-follicular allopregnanolone predicted worse depression and anxiety later in the cycle.
- Two to three cycles of daily mood tracking show whether the sadness is really tied to your follicular phase.

## Why do you feel sad in the follicular phase?

Right after your period ends, estrogen and progesterone are both close to the lowest point of your cycle.

- Progesterone stays near zero until after ovulation.

- Estrogen is only starting its climb.

A study of 29 women with and without PMDD found dysphoric mood rose more in the late luteal phase for women with PMDD than for women without PMDD (Hormones and Behavior, 2008). That's one reason follicular sadness gets less attention than premenstrual sadness, since for most people it isn't the cycle's low point.

Still, the hormone floor is real. A meta-analysis of 778 women found cortisol, the body's main stress hormone, runs higher in the follicular phase than in the luteal phase (Hedges' g = 0.13, p < 0.01, Frontiers in Endocrinology, 2020). Higher cortisol doesn't read as sadness for everyone. For some people it shows up as wired or on edge, and that can tip into low mood on a stressful week.

There's a slower piece too. Researchers measured allopregnanolone, a calming neurosteroid made from progesterone, in the mid-follicular phase in women with a PMDD-like mood pattern.

It was higher than in women without that pattern, and the higher it was, the worse depression and anxiety got later in the cycle (Archives of Women's Mental Health, 2025). For some, what happens here can shape the mood that follows in the luteal phase.

## Is sadness in the follicular phase normal?

Some dip in mood during the follicular phase is normal. Daily mood tracking across the menstrual cycle consistently finds cyclic variation, not a flat line, even in women who don't notice it themselves (Health Psychology, 1991). Well-being moved along with cycle phase in that study, and it was lowest in the days before the period for most women, not the days after.

That's worth noticing if your pattern looks different. A sadness that's worse in the follicular phase than anywhere else in your cycle is less typical, but it's not rare or alarming on its own. It can mean the hormone floor after your period affects you more than it does other people, or it can mean something else is going on that happens to land on these days this month.

One dip doesn't tell you much. A pattern across two or three cycles does.

Right now

What helps right now

- 1 Step outside for 10 minutes if you can. Energy tends to run higher in the follicular phase, so movement often helps more here than premenstrually.
- 2 Eat something with protein. Low blood sugar can feel like low mood and is easy to rule out.
- 3 Say the fact out loud: estrogen and progesterone are both near their lowest right now, and that's a real reason.
- 4 Write down the specific thing bothering you, separate from the mood itself, so you know what to act on later.
- 5 If you want somewhere to put it first, open Niyora's Moon and write what happened before deciding what to do.

Niyora walks you through this when it happens:

- Calm down

- See it another way

- Choose what to say

## When in the follicular phase is it worst?

The first few days after bleeding ends tend to be the hardest, when estrogen and progesterone are both still near their lowest. As estrogen rises toward ovulation, mood tends to lift for most people.

| Part of follicular phase | Estrogen | Progesterone | What's typical |
| --- | --- | --- | --- |
| Early (overlapping your period) | Low, just starting to rise | Near zero | Often the flattest mood of the phase |
| Mid (about a week after your period starts) | Rising | Near zero | Steadier for most, calmer for some |
| Late (the few days before ovulation) | High, peaking | Still low | Often the best mood of the cycle |

One study measured neurosteroid levels specifically in the mid-follicular phase and found a difference there in women with a PMDD-like mood pattern, which suggests the middle of this phase isn't just a quiet stretch for everyone (Archives of Women's Mental Health, 2025).

If your low days cluster right after your period rather than drifting through the whole phase, that timing itself is useful information to write down or bring to a doctor.

## Is it PMS or PMDD?

PMS and PMDD are both defined by timing, meaning symptoms in the days before your period that ease once it starts.

PMS covers physical or emotional symptoms in the one to two weeks before bleeding. PMDD is a diagnosis in the DSM-5-TR and ICD-11, with at least five symptoms, one of them a mood symptom, in the final week before the period, easing within days of it starting and minimal the week after.

Sadness that's worse in the follicular phase, after your period has started, doesn't fit either pattern by definition. That doesn't mean it isn't real. It might be an existing low mood or anxiety that's present all month and happens to be loud this week (sometimes called premenstrual exacerbation when it also worsens before the period), or it might be a reaction specific to the hormone floor right after bleeding ends.

| Pattern | When it shows up | Eases by |
| --- | --- | --- |
| PMS | 1 to 2 weeks before your period | Once your period starts |
| PMDD | Final week before your period | A few days after your period starts |
| Follicular phase sadness | After your period, before ovulation | Doesn't fit the premenstrual pattern, worth tracking separately |

If low mood is also present outside the follicular phase, that's a sign to look at the whole month, not just this one week.

## What helps right now?

You don't have to just wait this out.

- Get outside for 10 to 15 minutes. Energy and motivation tend to run a little higher in the follicular phase than the week before your period, so movement often helps more here.

- Eat something with protein within the hour. Low blood sugar can feel a lot like low mood, and it's an easy thing to rule out.

- Say the hormone piece out loud: estrogen and progesterone are both low right now, and that's a real, physical reason.

- Write down what's bothering you, separate from how you feel. Mood and cause aren't always the same thing, and sorting them tells you what's worth acting on.

Niyora is a PMS and PMDD support app. If you want somewhere to put the sadness before deciding what to do with it, Niyora's Moon lets you write what happened, see it from another angle and calm down before deciding what to do.

## How do you track it across cycles?

One cycle tells you almost nothing. Two or three tell you whether this is a pattern or a one-off.

- Note your mood on a simple 1 to 10 scale each day, along with the day of your cycle.

- Mark the day your period starts and ends, so you can see which phase you're in without guessing.

- Write one line about what else was going on that day: sleep, a fight, a deadline.

- After two cycles, look for where the low days cluster, using the [follicular phase](https://niyora.com/cycle/follicular-phase/) and [follicular phase hormones](https://niyora.com/cycle/follicular-phase-hormones/) pages to match your notes to what's rising or falling.

A cycle phase calculator or a hormone chart can show you roughly where you are without doing the math yourself. If the low days actually cluster in the week before your period instead, that's a different pattern, covered on the [luteal phase](https://niyora.com/luteal-phase/) page, and [how your cycle affects your mood](https://niyora.com/cycle/menstrual-cycle-and-mood/) walks through the bigger picture.

When to see a doctor

If this sadness takes a week of every month regardless of phase, or you have thoughts of hurting yourself, see a GP or gynecologist and bring two months of daily notes.

## Questions people ask

Is it normal to feel sad right after your period?

+

A little dip after your period is normal. Estrogen and progesterone are both near their lowest point in the first days of the follicular phase, and mood research finds mild cyclic variation across the whole cycle, including this part of it (Health Psychology, 1991). Most people's low point is still the week before the period.

Can low progesterone cause sadness in the follicular phase?

+

Progesterone stays near zero for most of the follicular phase, which removes one source of calming neurosteroid activity until after ovulation. On its own, low progesterone doesn't reliably predict low mood in healthy cycles, but combined with higher follicular cortisol (Frontiers in Endocrinology, 2020), it can make this stretch feel flatter for some women.

Why do I feel anxious instead of sad in the follicular phase?

+

Cortisol, the main stress hormone, runs higher in the follicular phase than in the luteal phase across a meta-analysis of 778 women (Frontiers in Endocrinology, 2020). For some people that reads as anxious or on edge rather than sad. The feeling can still be real even if it shows up as tension instead of tears.

Could follicular phase sadness be PMDD?

+

PMDD is defined by timing: symptoms in the final week before your period that ease within days of it starting and stay minimal the week after. Sadness that's worse after your period, in the follicular phase, doesn't fit that pattern on its own. Tracking two cycles shows whether your low days cluster there instead.

How long does follicular phase sadness usually last?

+

For most people, any follicular dip eases within the first several days after the period, as estrogen rises toward ovulation. Follicular phase sadness that lasts the whole phase, or that shows up every cycle at the same point, is worth two cycles of daily tracking.
