Why Perimenopause Symptoms Can Feel So Unpredictable

Last week, you couldn't sleep. You couldn't think straight. You snapped at the people around you, and you weren't sure why.

This week, you feel almost normal.

You are not going mad.

I hear some version of this every week in clinic. "I felt awful for two weeks. Now I feel fine. I don't know if I'm imagining it."

The worst part is not the bad weeks. The worst part is sitting in the quiet of a Sunday afternoon, wondering whether you are making the whole thing up.

You are not. There is a reason your symptoms come and go. Once you understand it, the self-doubt eases. That is what this post is for.

Sarah

Sarah came to see me after three weeks of awful sleep, rising anxiety, and brain fog so thick she had started writing everything down. She couldn't trust her memory.

By the morning of her appointment, she felt fine.

She sat down and said, "I feel ridiculous being here. You must think I'm wasting your time. I felt dreadful last week. Today I'm fine."

She is not the first woman to say this to me. She will not be the last.

A good day on the morning of your appointment does not cancel out three bad weeks. It just means perimenopause is doing what perimenopause does. The symptoms come. The symptoms go. The day you finally get an appointment is, by some quiet stroke of bad luck, often a day when you can almost convince yourself nothing is wrong.

Nothing was wrong with Sarah's appointment. Nothing was wrong with the way she described her symptoms. What is wrong is the idea that symptoms have to behave in a steady way to be real. They don't. And they are real.

Emma

Emma came in with a different version of the same problem. Hers was about her husband.

On the Monday before her appointment, she had been tired and tearful and could not concentrate. By Wednesday she was more or less herself. By Thursday she was back to feeling dreadful. Her husband, trying to be kind, said: "But you were fine yesterday. What changed?"

Her answer to him was: "I have no idea. That's the problem."

That is the problem. Not just for her, but for the people around her too.

Partners want to help. Children want a mum who is the same from one day to the next. People at work want to know what to expect from you on Monday morning. When you keep changing, everyone around you starts to feel unsure. So do you.

This part does not get said often enough. The ups and downs do not just hurt you. They put pressure on your relationships, because they don't make sense to the people who love you. If you are short with your husband on a Wednesday and warm with him on a Thursday, he can be forgiven for thinking he did something wrong on Wednesday. He did not. Your oestrogen was lower on Wednesday than it was on Thursday. He will not have learned that anywhere. You probably haven't either, until now.

What is actually happening in your body

Think of your hormones like a thermostat that has stopped working properly.

In your younger years, your oestrogen and progesterone followed a steady monthly pattern. The thermostat kept the temperature about right.

In perimenopause, the thermostat starts swinging. Oestrogen goes up one week, and you feel good. It drops the next, and you feel terrible. Some months, progesterone barely shows up. The pattern your body has used for twenty years has stopped working the way it did, and your body is trying to adapt.

Oestrogen and progesterone affect a lot more than your periods. They affect your sleep. Your mood. How well you can concentrate. Your energy. Even how hot or cold you feel.

When your hormone levels go up and down without warning, your symptoms do too.

It is not one thing going wrong. It is many parts of your body trying to keep up with signals that keep changing.

The most important thing to understand

The ups and downs are not a sign that something else is wrong.

The ups and downs are perimenopause.

You are not failing to find a pattern. There is no neat pattern to find. You are not missing a trigger you could have avoided. There is no single trigger. There is a process happening underneath you, and it does not follow the rules of a normal week.

The sooner you can stop blaming yourself for not making sense of it, the more energy you have for getting through it.

What helps

I am not going to give you a list of tips that "fix" the ups and downs. They cannot be fully fixed while you are still in perimenopause. But a few things help.

Knowing that the ups and downs are part of perimenopause takes the edge off the fear. You are not failing to spot something. There is nothing tidy to spot.

Saying it out loud to the people you live with helps too. A sentence like "I'm in perimenopause. My symptoms come and go. It is not about us. It is hormones" changes the conversation in a way that twenty arguments about why you are short-tempered never will. Most partners do not need you to be the same every day. They just need to know what is going on.

On the harder days, try not to add guilt on top of the symptoms. "I felt fine yesterday, why can't I cope today?" is a sentence that does not help you. "Today is harder, and that is what today is" helps more.

If keeping a note of your symptoms makes you feel more in control, do it. But do not expect a tidy pattern to appear. If the tracking starts to feel like another job you are failing at, stop.

You are not alone in this

The ups and downs are real. They are one of the hardest parts of perimenopause. Partly because they make you doubt yourself. Partly because no one around you knows what they are looking at either.

It does ease. Perimenopause is a stage, not a forever. On the other side, things settle.

If you have been quietly questioning yourself because your symptoms do not make sense, I hope this has helped a little.

You are not imagining it. You are not overreacting. There is a reason. It has a name.

The next post will be about why your blood tests so often come back normal even when you feel as if nothing in your body is working the way it used to.

Patient details have been changed. The story is real.
