This guide is general education that summarizes published research and guidance from groups like the American Academy of Pediatrics, the CDC, and the WHO. It isn’t medical advice, and every child develops on their own timeline. Your pediatrician knows your child; if something feels wrong, call them. In an emergency, call 911.

Fourteen weeks exactly. By the US count, the second trimester runs from week 14 through week 28, so this is its first day ([MedlinePlus](https://medlineplus.gov/ency/patientinstructions/000557.htm)). Today is about a small thing you might find and wonder about: a yellow stain in your bra.

## Your baby

Around 8.5cm long from head to bottom, about the size of a kiwi fruit ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-14/)). The head is becoming rounder and more in proportion with the body ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-14/)). The baby is kicking, but you probably won't feel it yet ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-14/)); the NHS's week 13 page says you may not feel movement until around week 17 ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-13/)).

## Your body

If you've noticed yellow stains in your bra, they are probably colostrum, your first milk ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-14/)). It isn't a sign that anything is early or wrong, and the NHS lists it alongside the other ordinary symptoms of the week, sore breasts included ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-14/)).

The bigger change this week may be how you feel in the mornings. Energy and appetite may return as nausea and tiredness ease ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-14/)); nausea and fatigue usually ease in the second trimester ([OWH](https://womenshealth.gov/pregnancy/youre-pregnant-now-what/stages-pregnancy)). If yours hasn't, that's within the range too: morning sickness may continue until the 4th month, and some women have it the whole pregnancy ([MedlinePlus](https://medlineplus.gov/ency/patientinstructions/000604.htm)).

## Try today

### The colostrum note

- **Time:** 2 minutes, when you notice it

1. If you spot a yellow stain, write today's date in the notes you keep for appointments. The NHS says it's probably colostrum, your first milk ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-14/)).
2. Nothing needs doing about it. A folded tissue or a breast pad in the bra is the whole fix.
3. If there's no stain, there's nothing to note. The page says a stain is probably colostrum; it doesn't say everyone gets one.
4. If it bothers you, say so at your next visit. MedlinePlus's rule for this trimester is to tell your doctor or midwife about any problems or concerns ([MedlinePlus](https://medlineplus.gov/ency/patientinstructions/000557.htm)).

**Make it work:** Put the note where the other firsts go. In a few months it will read as the first thing your body made for the baby.

## Watch for

- **Normal:** sore breasts, still on the NHS's list of symptoms this week ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-14/)). **Call your provider** for any bleeding; the NHS says to seek advice for any bleeding ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-14/)).
- **Normal:** nausea that's tailing off, or hanging on; it can last until the 4th month ([MedlinePlus](https://medlineplus.gov/ency/patientinstructions/000604.htm)). **Go to the ER** for severe nausea and throwing up: the CDC's threshold is being unable to drink for more than 8 hours or eat for more than 24 hours ([CDC](https://www.cdc.gov/hearher/maternal-warning-signs/index.html)).
- **Normal:** an appetite that comes back ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-14/)). **Call your provider** if you lose more than 2 pounds (1 kilogram) in a week, or if vomiting doesn't improve with home remedies ([MedlinePlus](https://medlineplus.gov/ency/patientinstructions/000604.htm)).

## For you

If the energy is back, you don't have to spend it on anything heroic. The NHS's to-do list for this week is modest: 150 minutes of exercise a week, starting with 10 minutes of brisk walking a day if that's where you are ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-14/)). Ten minutes outside counts.

If the appetite is back, eat what you want. The NHS says a varied balanced diet, with no "eating for 2" ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-14/)); that leaves a lot of room.

If you're the partner: this is the week to cook the thing she couldn't face in week 8. Ask first. The answer may still be no.
