What to Expect in the First 3 Months of Hormone Therapy

Starting is the hard part

Almost every woman I start on hormone therapy asks some version of the same question in the first two weeks: is this working, and is what I'm feeling normal?

So here's the timeline I give people up front.

Weeks 1 to 2

You may not feel much yet. That's expected.

What can show up early:

• Breast tenderness or fullness
• Mild bloating
• Some nausea with oral progesterone
• Drowsiness within an hour of taking progesterone at night — which is why I dose it at bedtime, and why some women find it's the first thing that helps their sleep
• Skin irritation at a patch site

Night sweats sometimes ease in the first ten days. Sometimes they don't move at all yet.

Weeks 2 to 6

This is where vasomotor symptoms — hot flashes and night sweats — typically start to break. Most women see meaningful improvement in this window.

Sleep often follows, partly because you're not waking up drenched, and partly because progesterone helps independent of that.

Mood, irritability, and the sense of having a shorter fuse tend to shift here too. Brain fog usually lags a few weeks behind sleep.

Early breast tenderness usually starts fading around week four to six.

Weeks 6 to 12

By month three I expect to know whether the dose is right.

What's still improving in this stretch:

• Vaginal dryness, discomfort with sex, and urinary symptoms. These are the slowest, and they need local vaginal estrogen in many cases even if you're on a systemic patch. Two to three months of consistent use before judging results.
• Joint aches
• Energy and exercise tolerance
• Libido — often the last thing to change, and sometimes it needs a separate conversation

About bleeding and spotting

Unscheduled spotting in the first three to six months of therapy is common, particularly on continuous regimens, and usually settles.

What isn't routine: bleeding that starts after you've been stable for months, bleeding that's heavy, or bleeding that persists past six months. Those get evaluated. NICE updated its guidance on unscheduled bleeding for exactly this reason — most of it is benign, but it shouldn't be ignored.

How I adjust

The starting dose is a starting point.

At follow-up we look at what improved, what didn't, and what side effects you're carrying. From there we might change the dose, change the route (a patch instead of a pill, or the reverse), change how progesterone is dosed, or add local vaginal estrogen.

I don't chase a number on a lab. In menopausal hormone therapy, symptom response guides the dose in most situations. Levels have a role in specific cases — poor absorption, unusual symptoms, testosterone monitoring — not as a routine target.

When to reach out rather than wait

Call or message me for:

• Chest pain, shortness of breath, or coughing up blood
• New severe headache, especially with visual changes
• Calf pain, swelling, warmth, or redness in one leg
• Sudden weakness or numbness on one side, or trouble speaking
• A new breast lump
• Heavy bleeding, or any bleeding that soaks through protection

Otherwise, side effects that are annoying but stable — tenderness, mild bloating, a patch that itches — are worth a message but not an emergency. Most of them are fixable with a small change.

The bottom line

Give it three months before deciding whether hormone therapy is working for you, but don't spend those three months guessing.

Direct messaging between visits exists precisely so you can ask "is this normal?" the week it happens instead of waiting.
