Week 6 — A Heartbeat You Can Actually See
Overall Pregnancy
Your Baby is About

Your baby is now the size of a sweet pea — about 5–6mm — and this week brings one of the most jaw-dropping early milestones: a visible heartbeat. The heart is already beating at around 110 beats per minute and can be detected on a vaginal ultrasound. Tiny arm and leg buds are sprouting from the sides of the body, and the beginnings of eyes, ears, and a nose are starting to take shape.
Week 6 is often when pregnancy symptoms really kick in — nausea affects around 80% of pregnant women in the first trimester, and about half experience vomiting too. Breast changes are very common: tenderness, darker nipples, more visible veins. Some people notice they're producing more saliva than usual, which is totally normal. If you're losing a bit of weight because eating feels impossible, that's okay — your baby is still getting everything it needs.
At 6 weeks, your baby's heart is beating at about 110 beats per minute — and by Week 9 it will peak at around 170 bpm. That's nearly three times faster than a resting adult heart. The reason it beats so fast is that a tiny heart needs rapid pumping to move blood efficiently through such a small system. It will slow down gradually as the heart grows bigger and stronger.
If smells are suddenly making you gag, try switching to cold meals — cold food has much less smell than hot food. Ginger is genuinely proven to help with nausea: ginger tea, ginger biscuits, ginger ale, or ginger capsules. It won't eliminate nausea but it takes the edge off for most people.
Cold foods smell less than hot foods — this is a practical nausea hack. Smoothies, cold pasta salads, cheese and crackers, and fruit can be much easier to tolerate than a cooked meal.
