Sexual development continues. The external genitalia are more developed, and it is becoming easier to determine male from female by looking at external genitalia. Skin tags are small tags of skin that may appear for the first time or may grow larger during pregnancy. Moles may appear for the first time during pregnancy, or existing moles may grow larger and darken during pregnancy. If a mole changes, it must be checked.
Some women are concerned about tests that use radiation during pregnancy.
Your baby continues to change. Ears and eyes move to a more normal position by this week. I remember getting a call from Lucy, who was in the emergency room. She had fallen in her driveway and hurt her ankle. There are valid medical reasons for X-rays, but in each case, the need must be weighed against the risk to a pregnancy.
