What typically happens at 6 weeks

Cardiac activity may be visible on a transvaginal ultrasound around now. Early symptoms such as nausea, tiredness and tender breasts commonly start or intensify.

In the first trimester, the body is adjusting quickly to rising pregnancy hormones. Tiredness, nausea and breast tenderness are common, although some people notice very few symptoms. At 6 weeks you have about 8 weeks to go until the second trimester begins at 14 weeks.

Every pregnancy is different, and the timing of tests and appointments depends on your healthcare provider and country. If something worries you — for example bleeding, severe pain, fluid leaking or, later in pregnancy, a change in your baby’s movements — contact your midwife, doctor or maternity unit straight away.
