Twenty-two weeks and three days. Skin that's stretching tends to itch, and most of the time that's all it is. Today's note gives you one simple rule for the times it might be something else.

## Your baby

Around now your baby is around 27.8cm long from head to toe, about the size of a sweet potato ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-22/)). Their lungs are developing, and they practise breathing in the womb ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-22/)). It's rehearsal: even at 24 weeks, the OWH says, the lungs are formed but not yet working ([OWH](https://womenshealth.gov/pregnancy/youre-pregnant-now-what/stages-pregnancy)).

## Your body

About 20 percent of pregnant women feel itchy during pregnancy, and it typically goes away after delivery ([OWH](https://womenshealth.gov/pregnancy/youre-pregnant-now-what/body-changes-and-discomforts)). The NHS suggests unperfumed moisturiser, loose cotton clothing and cool baths, and says to seek advice if the itching gets worse, especially at night ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-15/)). MedlinePlus adds: avoid perfumed products on itchy skin, and talk with your provider before taking an antihistamine ([MedlinePlus](https://medlineplus.gov/ency/patientinstructions/000611.htm)).

Then there's the one exception. Itching that keeps going without a rash should be reported to your provider, because it may indicate a condition called cholestasis ([MedlinePlus](https://medlineplus.gov/ency/patientinstructions/000611.htm)). Late in pregnancy, the NHS puts severe itching at night on its list of signs to call about immediately ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/3rd-trimester/week-39/)). It's easy to check, which is why the rule exists.

### The itch-without-rash rule

- **Time:** 2 minutes

1. Next time you itch, look at the skin. Is there a rash, or does it just look like your skin?
2. Itch with a rash, or itch over the stretching bump: unperfumed moisturiser, loose cotton, a cool bath, and watch it ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-15/)).
3. Itch with no rash that keeps going, or itching that's worse at night: call your provider ([MedlinePlus](https://medlineplus.gov/ency/patientinstructions/000611.htm)).
4. Write the rule on your fridge card in five words: "No rash, keeps itching: call."

**Make it work:** Don't reach for an antihistamine or a medicated cream first. Ask your provider before taking anything ([MedlinePlus](https://medlineplus.gov/ency/patientinstructions/000611.htm)).

## Watch for

- **Normal:** an itchy bump and itchy stretch marks that calm down with moisturiser ([OWH](https://womenshealth.gov/pregnancy/youre-pregnant-now-what/body-changes-and-discomforts)). **Call your provider** for itching that keeps going without a rash ([MedlinePlus](https://medlineplus.gov/ency/patientinstructions/000611.htm)).
- **Normal:** itching on a warm evening that settles after a cool shower. **Call your provider** if the itching worsens, especially at night ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-15/)).
- **Normal:** dry, itchy skin from scented soap or a new detergent. **Call your provider** before taking an antihistamine for it ([MedlinePlus](https://medlineplus.gov/ency/patientinstructions/000611.htm)).
- **Normal:** a list of signs that doesn't quite match what you feel. **Call your provider** if you feel like something just isn't right; the CDC says to contact them if something seems wrong, even if it isn't on the list ([CDC](https://www.cdc.gov/hearher/maternal-warning-signs/index.html)).

## For you

Most itching is just itching. Most skin changes in pregnancy are normal and resolve afterward ([MedlinePlus](https://medlineplus.gov/ency/patientinstructions/000611.htm)). You don't need to inspect yourself every hour; the rule is there so you never have to wonder for long.

If you're the partner: if you notice her scratching in the night, say so in the morning. Night-time itching is the kind worth mentioning.
