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


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.
