10 weeks pregnant

At 10 weeks pregnant, the embryo becomes a fetus, and the heartbeat may be heard with a handheld Doppler. You're in the first trimester, about 8 weeks after conception, because pregnancy is counted from the first day of your last period.

What's developing at 10 weeks

  • The eyelids are more developed and begin to close, and the outer ears begin to take shape.
  • The facial features become more distinct, and the intestines rotate.
  • At the end of week 10, the embryo is called a fetus, the term used until birth.

Around week 10, a doctor may be able to hear the heartbeat with a handheld Doppler, a small device placed on the belly.
