Tracking combined oral — sequential
A daily tablet whose composition changes partway through each 28-day pack: estrogen-only first, then estrogen plus progestogen. The switch day differs by product, and sequential regimens usually produce a monthly withdrawal bleed.
- Schedule
- One tablet every day; the composition switches on a product-specific day (Femoston on day 15, Elleste Duet on day 17).
- UK names
- Femoston 1/10, Elleste Duet
- Route
- oral
- In Perity
- A daily schedule with an explicit progestogen-phase start day — product-specific, never assumed.
What to log
- The pack does the phase-keeping; your record should still know the switch day, because symptoms that cluster after it are a pattern worth showing.
- Log the withdrawal bleed as expected rhythm.
- Never assume the switch day from another product — Femoston and Elleste Duet differ, and your record should match your pack.
Questions
Do I need to track anything if the pack already sequences itself?
The pack keeps the schedule; it doesn't keep your symptoms. The overlay — what you felt, dated, against which phase the pack was in — is the part only you can record, and the part appointments actually use.
My bleed pattern changed. What matters for the appointment?
Dates: when bleeds start relative to the phase switch, how long they run, what changed. That's a clinician conversation worth having with a dated record rather than a recollection.
