Quick answer: At 8 weeks pregnant, your baby is about the size of a raspberry, about 1.6 cm (0.6 in) long. You're in the first trimester, in month 2, with 32 weeks to go until your due date. This week's milestone: end of embryo's first stage. Symptoms vary from person to person.

Your baby at 8 weeks
Your baby is about the size of a raspberry. ACOG says that by the end of week 8, the embryo is about half an inch long. Webbed fingers and toes are appearing, and the digestive tract is taking shape.
Your body at 8 weeks pregnant
Your uterus is growing, although it is unlikely to show yet. Many people feel bloated, tired and nauseous this week.
Things to do this week
- Attend your first prenatal or booking appointment, often between 8 and 12 weeks.
- Bring your last period date, medicines list and health history.
- Ask how to contact your care team between visits.
When to call your doctor or midwife
Contact your care team straight away if:
- you have vaginal bleeding, especially with cramps or belly pain
- you have severe or one-sided belly pain, or pain in the tip of your shoulder
- you are vomiting so often you can't keep fluids down (the CDC flags being unable to drink for more than 8 hours)
- you have a fever of 100.4°F (38°C) or higher
- it hurts or burns when you pee
If something feels wrong, trust that feeling and call. In an emergency, call your local emergency number.
