6 weeks pregnant
First trimester about 1 month
At 6 weeks pregnant, your baby is about the size of a sweet pea.
Baby this week
About 5–6mm. Facial features are beginning to form — tiny indentations where eyes and nostrils will be. Arm and leg buds are visibly growing.
Did you know? The embryo's heart is now beating 100–130 times per minute and may be visible via transvaginal ultrasound this week.
What she may be feeling
- Morning sickness (often all-day)
- Strong food aversions
- Excess saliva
- Breast changes continue
- Bloating
- Headaches
- Fatigue
- Mood changes
Tips for her this week
- Try small, frequent meals to combat nausea — an empty stomach often makes it worse.
- Ginger (tea, candies, capsules) can genuinely help with nausea.
- Stay hydrated even if it's hard to keep things down.
- A transvaginal ultrasound this week may show a visible heartbeat for the first time.
For partners
- Morning sickness often peaks this week — be patient and non-judgmental even when she can barely eat.
- Keep plain crackers, ginger tea, and whatever works for her stocked at all times.
- Her sense of smell is heightened — be mindful of strong colognes, cooking smells, and cleaning products.
- If she's struggling at work due to fatigue or nausea, help her think through how to manage it.
Partner to-do list
- Stock nausea remedies: ginger tea, plain crackers, peppermint
- Confirm first prenatal appointment is booked
- Take over cooking this week entirely
- Read a chapter of your dad book
This week together
- Discuss whether to share news at 8 weeks or wait until 12
- Start thinking about finances: parental leave, childcare budget
- Try to attend the first ultrasound together if possible
When to call your doctor or midwife
Contact your care provider right away, or call emergency services, if she has:
- Inability to keep any fluids down for 24+ hours — this may be hyperemesis gravidarum
- Severe vomiting requiring medical attention
- Painful urination (possible UTI — common in pregnancy)
