Clinics often send a first order sized for a typical stim length. Your response can be longer or shorter. Doses can change after monitoring. That is why people end up counting pens and vials mid-cycle instead of assuming the box will last.
Running low is common. Threads on patient forums show the same pattern: day 7 or 8 arrives, someone opens the fridge, and the remaining Gonal or Menopur will not cover the next night plus a weekend. The scramble that follows is stressful and avoidable if the count is visible before the pharmacy closes.
Why the first order is rarely exact
Stim length is not fixed in advance. Follicle growth, estradiol levels, and clinic protocol decide whether you trigger on day 9, 11, or later. Many clinics intentionally order on the conservative side so you are not left holding unused, non-returnable medication. The trade-off is that you become responsible for watching the remaining stock and requesting a refill early enough for shipping or local pickup.
Dose adjustments compound the problem. A jump from 150 to 225 or an extra day of antagonist can erase the buffer you thought you had. Pens that look full may contain less usable volume than the label suggests once you account for priming and residual drops.
A practical way to count what you have
Keep one running total per medication, not a mental note. After each dose, subtract the units or vials used. Note the date you opened a multi-dose pen if your clinic or pharmacy gives an in-use window. When the remaining amount equals roughly two days of your current dose (or covers a weekend if the next monitoring day is Friday), treat that as the reorder signal.
Ask the nurse at the next monitoring visit how many more nights they expect. That number, combined with your actual remaining stock, is more useful than the original prescription quantity. Some clinics keep a small emergency supply on site; others expect you to use the specialty pharmacy. Confirm the path before you need it after hours.
If you travel or live far from the clinic, build in shipping lead time. Same-day local options exist in some cities; they are not universal. Knowing your pharmacy’s cutoff and your clinic’s after-hours process removes the worst of the panic.
What belongs in an inventory view
A useful record shows the medication name, current remaining amount (units or vials), and how many nights that covers at today’s dose. It should update when you log a dose so the number is never stale. Linking inventory to the same schedule that drives reminders keeps the two lists from drifting apart.
Cove includes medication inventory alongside dose reminders and injection-site tracking. You can see how much is left and how many nights it covers without opening a separate spreadsheet. The goal is fewer last-minute calls, not medical advice about dosing or ordering.

When the count is low
Contact the clinic or specialty pharmacy during business hours as soon as the remaining stock looks tight. Do not wait until the evening of the last dose. If the pharmacy cannot deliver in time, ask whether the clinic has any on-hand medication that can bridge one night while a refill ships. Patient-to-patient sharing is common in private groups; it is not a reliable plan and carries its own risks around storage, labeling, and legality.
Keep the original packaging and any lot numbers until the cycle ends. If a refill arrives with a different presentation (smaller pen, different vial size), update the inventory entry so the remaining-nights calculation stays honest.
An accurate count does not change the protocol. It only reduces the chance that a shipping delay or a longer stim turns into a missed dose. That is a logistics problem, and it is solvable with a short daily habit.
