My wife has hyperemesis at 5 months—vomi

Don't wait for Monday: take her to a door that is open tonight — the urgent care you have, or better, her maternity/labour-and-delivery triage or the OB's after-hours line — and say early: "she's about five months pregnant and can't keep fluids down."

I'm not diagnosing her and I won't change anything she's been prescribed. But I'd say this much: vomiting 5–12 times a day with weight loss is past "wait and see," and the standard thing a clinician should do about it is see her, check her, and give a written plan — fluids, bloods, and a pregnancy-safe anti-sick medicine decided by them, not by us. Getting that done tonight protects the pregnancy, the marriage, and Monday's appointment all at once.

One thing that changes the door, not the plan: urgent care is fine for the door tonight, but if they say "this is pregnancy, go to your OB on Monday," that is not the end of it. Ask them to transfer you, or to call the maternity unit themselves. If you can get the labour-and-delivery triage desk on the phone, that is a better first call than a general urgent care.

1. What you've already tried, and what to do instead

Waiting it out, because the doctor said it's normal morning sickness — that was following instructions, not a mistake on your part. What to do instead: the log becomes the argument. Normal morning sickness does not usually come with weight loss. Right now the log is the thing that moves her from "it's normal" to "she needs to be seen today."

Three levers you actually hold:

Get her seen, not a debate won. The aim today is an assessment and a written plan, not for the doctor to admit they were wrong. A nurse or midwife at a triage desk can often move this faster than the OB's front desk can.

Insist on the things that only a clinician can do. Say: "Could you check her fluids and electrolytes, and tell me what the plan is if she can't keep fluids down?" That is not you diagnosing. It is naming what a visit has to produce.

Ask for a plan in writing — what to take, what to do if the next vomit comes, what would send us to an emergency department, and when she is reviewed. A written plan is also the thing that makes the next phone call easy instead of personal.

2. The next 25 minutes, tonight (screenshot-friendly)

• Set out the things you already have, in one place: her electrolyte drink or ready-mixed rehydration sachet, the dry crackers, a cup with a lid and a straw if she has one, her pregnancy notes, her medicine bottles (or clear photos of the labels), and the scale if you have one.
• Write five lines on paper or your phone, take a photo of it: today's date, roughly how many times she's vomited, what she last managed to keep down and when, the last time she passed urine, and her last known weight. That photo is the whole argument at the door. Add a line for anything you gave her and when.
• Routines, not meals. Small sips of cool fluid taken a minute or two at a time, sitting up or lying slightly propped — no forcing a plate, no "just try one more bite" while she's nauseated. Dry crackers before she sits up tend to be easier than a full meal. Whatever she manages, you write down.
• Handle the school week in one call, not ten. If there's an elder or a sibling nearby, that is your ride and your childcare in one. Make that one message now, while you're calm, so tonight isn't a scramble.
• You are allowed to be the logistics person tonight, and nothing else. Count, carry, log, drive. That is the job.

3. Scripts you can copy

To the door, at triage or urgent care, first ten seconds:
"She's about five months pregnant. She's been vomiting five to twelve times a day, she's lost weight, and she can't keep fluids down. Could she be assessed today, and is there a maternity or obstetric team you can involve?"

If they say it's normal pregnancy sickness:
"Normal morning sickness doesn't usually come with weight loss. Could you check her fluids and electrolytes, and write us a plan for if she can't keep fluids down?"

If they push you to wait for Monday:
"What would need to change for her to be safe until Monday? And if that happens at two in the morning, which door do we use?"

Text or portal message to the OB, sent tonight, factual and short:
"Hi — [name] is five months pregnant. She has been vomiting 5–12 times a day and has lost weight. Attached is a log of the last 24 hours. Could she be seen Monday, and could you confirm in writing what the plan is if she can't keep fluids down before then?"

If you want a second opinion without burning the relationship:
"Is there someone else on the team who deals with pregnancy sickness like this? We don't want to wait if this turns into a drip or a hospital stay."

That last one is a request for a colleague, not an accusation. Most doctors hear it as sensible.

4. What to avoid

• Don't use anti-sickness medicine that wasn't prescribed for her, including leftovers from a previous pregnancy, a friend's, or anyone else's. Same for anything bought online.
• Don't add powders, supplements, herbal remedies or "hydration" products on your own in pregnancy. If she wants something new, that's a pharmacist or her clinician's question, not a kitchen decision.
• Don't change, double, or skip anything her prescriber gave her. Take the medicines as prescribed; if it isn't working, that's a conversation for tonight's visit, not an edit at home.
• Don't treat a home scale, thermometer or blood-pressure reading as a green or red light by itself. Write the reading down and take it with you; it doesn't make or break the decision.
• Don't push food, don't clean her mouth while she's mid-vomit, don't argue about whether it's "really that bad." The counting is the evidence.
• Don't let her drive, and don't leave her alone in the bathroom if she's dizzy on standing.

5. Red flags — stop the home plan and go now

If any of these are true, skip the plan above: call your local emergency number or go to the nearest emergency department now, and say "pregnant" in the first sentence.

• She is dizzy, faint, or has to hold the wall when she stands
• She has barely passed urine all day, or it is very dark
• She is drowsy, confused, or unusually hard to wake
• She cannot keep any fluid down at all
• Vomited blood, or coffee-ground brown vomit
• Bad belly pain, or a fever with shaking
• A fast, pounding heartbeat, chest pain, or trouble breathing
• A severe headache with blurred vision, or sudden swelling of face or hands
• One-sided calf pain or swelling

I don't have your location — which country or city are you in? I won't guess a number from your language.

6. A one-page sheet for the door

The timeline, weight, and what you did tonight, laid out so you can hand it over and stop talking: 就诊单-妊娠呕吐-5months-4befcd20.pdf

What success looks like in 24 hours — not a cure, just the ground gained: she was assessed tonight, she has medicines and instructions in writing, and Monday has a booked review instead of a phone call. If she's keeping a bit more down by morning, that's a good sign; if she's keeping nothing down and passing little urine, that's the red-flag list, not a "let's see how Monday goes."
