Tracking palpitations on micronized progesterone
You're using micronized progesterone, and you want to know what palpitations is doing around it. That takes two records on one timeline — here's how to keep both so the overlay is worth something at your next appointment.
The symptom side
Palpitations are frequently reported around hormone swings and often co-occur with vasomotor episodes and anxiety spikes. They're also the symptom most worth being appropriately careful about — common in the transition, but never automatically dismissed as 'just hormones.'
The micronized progesterone side
The schedule is the anchor: which nights you take it — every night on a continuous regimen, or a block of roughly twelve nights a month on a cyclical one. The full schedule facts, sources included:
- Micronized progesterone — cyclical — A block of 12 nights (guidelines allow 12–14), at bedtime — anchored either to calendar dates (days 1–12 of each month) or to your cycle (from day 15), per BMS guidance.
- Micronized progesterone — continuous — Every night, at bedtime. This is BMS/NHS guideline practice rather than the product label — worth knowing, not worrying about.
How to run the record
- Log each progesterone night as it happens — on a cyclical regimen, the block's start and end dates are the anchors everything else reads against.
- Log episodes when they happen: time, severity, and what you were doing.
- Palpitations arrives in episodes, which is a gift to tracking: every logged episode carries a timestamp, and the on/off rhythm of progesterone nights gives the timeline its structure. Episodes that keep landing in the same place relative to it are exactly the pattern memory smooths over and a dated record preserves.
- When anything changes — dose, product, schedule — the change date splits your record into before and after. That comparison is the entire point of keeping it.
What the overlay can show
Alignment, not cause: Perity lines your palpitations entries up against the on/off rhythm of progesterone nights and shows you where they cluster — before and after any change, split by cycle phase where that's relevant. It never tells you why, and it never suggests what to do about it. It hands you dated evidence; the interpretation happens in the appointment, with your clinician.
Questions
Does micronized progesterone help with palpitations?
That's a question for your prescriber — Perity doesn't do efficacy claims, about anything. What Perity gives you is your own before-and-after: palpitations entries, dated and phase-tagged where relevant, either side of every change. That record is how the question gets answered for you specifically, rather than in general.
What if my prescriber changes the dose or product?
Update the schedule in Perity the day it changes. Your record splits into before and after automatically — symptom counts either side of a dated change are the cleanest evidence a follow-up appointment can ask for.
Perity informs, never prescribes — decisions belong with you and your clinician.
