They're starting to form, still joined by webbing for now.

It now has four chambers and beats around twice as fast as yours.
Movement
Small, spontaneous movements have begun.

What you might notice

  • Tiredness at its peak for many people. Rest when you can; it usually lifts in the second trimester.
  • Vivid dreams, often from hormones and broken sleep.
  • Heartburn, even this early, as the valve at the top of your stomach relaxes.
  • Your clothes feeling tighter around the waist, mostly from bloating.

Call your midwife, doctor or early pregnancy unit today if

  • You have bleeding, or cramping pain low in your belly
  • You have sharp pain on one side, pain in the tip of your shoulder, or you feel faint
  • You're being sick so often you can't keep fluids down
  • You have a fever, or it burns or stings when you pee

If the pain is severe or you feel faint, call emergency services.
