First Trimester:

We Have Lift Off

The first trimester lasts up to 12 weeks of a pregnancy.  This can be the most difficult as levels of the pregnancy hormone change rapidly.  Some women escape this stage without suffering any morning sickness but others may find themselves nauseous all day.

Either way, you may feel exhausted, your mood may change, you may have tender breasts or you could experience cravings and heartburn. Once your hormones level out, which is normally around the 12th week of pregnancy, some of these symptoms may subside.

In the meantime, your baby’s brain, spinal cord, heart, major organs, arms, legs and external genitalia will have begun to form. By the 12th week of pregnancy, your baby’s muscles will begin to work together.

During this period you will have your first antenatal appointment. You can start thinking about where you would like to give birth.

You will be offered a range of screening tests in early pregnancy. The tests are offered to try and find health problems that may affect you or your baby. But it is your choice to accept or decline the tests. To help you decide we recommend you read "Screening Tests For You and Your Baby", before your first midwife appointment.  

Ways to access the "Screening Tests for You and Your Baby" information are outlined below.
