Alone in a hotel room after a 63-egg retrieval, one donor felt a "bubble" near her collarbone.
Fluid was pushing against her lungs.
Clinic websites say "closely monitored."
They don't say what to watch for once you're alone.
These five signs are worth knowing before you sign anything.
1. The recovery feels too easy
One donor had a painless retrieval and went back to work quickly.
Days later, she had gained 10 pounds in 48 hours.
Donors describe symptoms that start two to three days after retrieval.
Others say things kept getting worse over the following two to five days.
So feeling fine on day one tells you very little about day four.
Most people read the first 24 hours as the finish line.
It isn't.
Ask at screening how long the clinic checks on you after retrieval, not just before it.
2. The bloating builds instead of fading
Feeling bloated and uncomfortable right after retrieval is common.
Donors describe something different: bloating that keeps climbing.
One donor received both hCG and Lupron as a dual trigger.
She later developed significant bloating and abdominal fluid.
Another needed that fluid drained.
Several donors were told a Lupron trigger makes OHSS "very unlikely" or even "impossible."
They developed severe OHSS anyway.
Lowering risk is not the same as removing it.
So you want to know your trigger in advance, and you want the reason behind it.
The final call often waits on your estrogen and follicle response late in the cycle.
That's why the better question is what result would change the plan.
If you're already mid-cycle and wondering whether to buy Lupron yourself, stop.
That's a clinical decision, so ask the clinic.
Asking isn't second-guessing your doctor.
It's how you find out what the plan is.
3. A bubble near the collarbone, or pain on a deep breath
The hotel donor described it as a "bubble" near her collarbone.
She was alone, and the fluid was pressing against her lungs.
Another donor reported pain on deep breaths and severe bloating.
Another said fluid pushed on her organs until she struggled to breathe.
She needed ER evaluation.
One donor retrieved 53 eggs and spent four days in the ICU.
She called the feeling "literally drowning to death."
Another was hospitalized for chest pain from pleural effusion and pulmonary edema.
Bloating is uncomfortable, but a change in your breathing is a different kind of signal.
Ask the clinic to write down which symptoms mean call us and which mean go to the ER now.
But what if you call, and the person on the line has a number in mind?
4. A number on the phone outweighs what you feel
An after-hours clinician told one donor to call back only if she gained more than 5 pounds.
She had trouble breathing, severe bloating, and worsening pain.
An ER CT scan later diagnosed OHSS.
She says the clinic tried to downplay her symptoms, and she faced $11,000 in financial fallout.
Another donor reported severe bleeding and low blood pressure.
She says a nurse told her to wait, suggesting ER doctors "wouldn't be able to help."
Others describe difficulty walking and urinating while being told it sounded manageable.
Donors in these stories say they felt the clinic wasn't taking them seriously because they were donors.
A scale can't measure pain on a deep breath.
If you're asking yourself "what if it's nothing," notice that commenters on these posts urged emergency care.
Ask before you start what the clinic's threshold is, and who decides when you go to the ER.
Then ask what happens if you're not near home when it counts.
5. Nobody gave you a plan, and you're far from home
The hotel donor had no clinical support nearby when it started.
Nobody had spelled out what she should do at that hour.
If you travel for a cycle, ask before you sign what the after-hours protocol is for someone staying away from home.
Ask what happens, medically and financially, if you're hospitalized there.
Then bring the rest of your list.
Ask which trigger you're likely to get, and why.
Ask what OHSS rate the clinic tracks, and what its prevention plan is.
Ask whether cabergoline (Dostinex) is used.
One donor with high estradiol started it around trigger day.
Ask what monitoring result would change your dose or protocol.
That last one matters if you respond well.
One donor's strong first response led to a higher dose in her second cycle.
Her second cycle brought worse OHSS, fainting, and exhaustion.
Nobody had warned her.
Now the part that stops you.
Will they think you're difficult?
Wanting to be a "good donor" who doesn't complain is common.
It's also how symptoms get swallowed until they can't be.
One donor asked her case manager what steps would be taken to prevent OHSS before agreeing to proceed.
Another was told there had "never been cases" of hyperstimulation at that clinic.
She backed out before her first injection.
A donor with a hospitalization-level OHSS history spoke up in advance.
Her next cycle was symptom-free.
A clinic that answers plainly loses nothing from your questions.
A clinic that brushes them off has just answered them.
Write the list tonight, and take it with you to screening.
