After egg retrieval, many people feel bloated and crampy for a few days. Warmth is a common comfort measure, but ask your clinic whether heat is fine for you before you use any of the options below. Some clinics prefer you avoid direct heat on the abdomen in certain situations, such as when you are at risk of ovarian hyperstimulation (OHSS) or when you are in the days after an embryo transfer.
Heating pad vs hot water bottle vs wheat bag vs patches
| Type | Needs | How long it stays warm | Control over temperature | Good for |
|---|---|---|---|---|
| Electric pad | Plug point | As long as it is on | Adjustable | Resting at home |
| Hot water bottle | Hot water | One to two hours | Starts hot, fades | Power cuts, bedtime |
| Wheat bag | Microwave | Short | Set by heating time | A quick, soft warmth |
| Adhesive patch | Nothing | Several hours | Fixed | Travel, the ride home |
Which one to pick
- One purchase for the whole week: an electric pad with auto shut-off. You can lower the heat, and you will not fall asleep on something that stays hot.
- Frequent power cuts: a hot water bottle with a thick cover, as a backup to the electric pad.
- Hospital day and the ride home: a couple of adhesive patches stuck to your clothes, if your clinic is fine with heat.
The four options
Product types to search for. We have not tested them, and we are not recommending a brand.
Electric heating pad
Best for: Steady, adjustable warmth while resting at home
Holds an even temperature for as long as it is on, and you can turn it down. Needs a plug point, so it stays near the bed or sofa.
What to look for
- Several heat settings
- Automatic shut-off
- Washable cover
- Long cord
Rubber or silicone hot water bottle
Best for: Cordless warmth, including a power cut
Needs no electricity and costs little. It cools within an hour or two and has to be refilled with hot water, which needs care.
What to look for
- A thick fabric cover
- A well-fitting stopper
- Manufacture date on the bottle
Microwavable wheat or seed bag
Best for: Moist, moulding warmth without a plug or boiling water
Warmed in a microwave for a short time, then draped over the abdomen or back. Heat lasts a short while and you need a microwave.
What to look for
- A natural fabric cover
- Clear heating instructions
- Washable outer cover
Self-heating adhesive warming patches
Best for: Travel, the car ride home, and a day out
Stick to clothing, not skin, and warm up on their own for several hours. Single use, so they add up if you rely on them.
What to look for
- Meant to be stuck to clothing, not skin
- Stated heating duration
- A clear temperature warning
Safety basics for any heat source
- Keep a layer of cloth between the heat and your skin.
- Do not fall asleep on an electric pad unless it has auto shut-off.
- Never fill a hot water bottle with boiling water; let the kettle sit for a minute first.
- Stop if the skin turns red or you feel any burning.
