The 8-week scan is one of the most anxiety-laden appointments in early pregnancy. The fear of walking in and not hearing a heartbeat is real and widely shared. Here's what helps: a heartbeat confirmed at 8 weeks drops your miscarriage risk to roughly 3%. Nausea that's getting worse right now — not better — is actually a reassuring sign that hCG is still rising. Feeling terrible at 8 weeks is, counterintuitively, a good sign.
This is when many women have their first prenatal visit. You may hear the heartbeat via Doppler.
What happens at your 8-week appointment shapes the roadmap for the entire first trimester — here's exactly what to expect.
By week 8, all major organ systems are present in miniature form. The embryo has increased in size over 1,000-fold since fertilisation — the most explosive growth phase in human life.
Pregnancy mood swings are biological, not psychological weakness. Estrogen fluctuates more dramatically in the first trimester than at any other point in life.
Most providers schedule the first prenatal appointment between weeks 8–10. If you haven't booked yet, do it now — this appointment establishes your care pathway for the entire pregnancy.
What happens at the first prenatal appointment:
What to bring: List of medications, family medical history (including genetic conditions), ID, insurance information, and any previous pregnancy records.
The 12-week scan is in approximately 4 weeks. See week 12 for what to expect at the nuchal translucency scan.

First prenatal appointment (booking visit): blood tests, urine, blood pressure, weight, medical history. Usually 45–90 minutes.
What should you do right now?
ACT NOW = call provider or go to hospital · MONITOR = watch and note · NORMAL = expected, no action needed
At 8 weeks, your baby is approximately 0.63 inches (1.6 cm) long and weighs about 0.04 oz (1 g) — roughly the size of a raspberry. The heart is beating 150–170 times per minute, and tiny arms and legs are clearly visible.
Common symptoms at 8 weeks: nausea (often at its worst between weeks 8–10), intense fatigue, breast tenderness and growth, metallic taste, heightened sense of smell, frequent urination, food aversions, bloating, and mild headaches. Symptoms vary widely — some women feel little at 8 weeks.
Most providers schedule the first prenatal appointment between weeks 8–10. At this appointment you'll have blood tests, urine tests, blood pressure measurement, medical history review, and a discussion about your pregnancy care options. If you haven't booked yet, contact your GP or OB this week.
Yes — at 8 weeks, an ultrasound clearly shows the baby with a visible, flickering heartbeat. Limb buds are visible. Most private early-pregnancy scans happen at 8–10 weeks for this reason. The NHS/routine dating scan typically happens at 11–13 weeks (the nuchal translucency scan).
Light spotting (implantation-style) can occur after sex or a pelvic exam and is usually not serious. Heavy bleeding, bright red blood, or bleeding with cramping should be assessed by your provider immediately. Most early pregnancy bleeds are not miscarriages, but assessment provides reassurance and rules out ectopic pregnancy.
