You are now 28 weeks pregnant, which is the beginning of week 29.

Your baby has grown to be about 38 cm long from head to toe (15 inches) and approximately 1,200 grams (1.2 kg) in weight (2lbs 10 oz).


Your baby's bones are now mature enough to start producing their own blood supply from their bone marrow, taking over this task from their liver and spleen. Their liver starts to store iron supplied from your body. This is Nature's way of meeting a newborns iron requirements for the first 6 months after birth, until they start eating solids.


This week marks the beginning of the 3rd trimester (the final 12 weeks of pregnancy). Your baby is regarded as being born on time if they arrive between 37 and 42 weeks - but remember, only about 5% of babies are born on their actual due date! During these final weeks your baby's main task is to mature their body systems, grow stronger and put on weight. Premature babies born at this stage of pregnancy have a good chance of survival. However, the closer they are born to 37 weeks, the more likely they will be well and healthy and not require advanced medical treatments.


Physical changes


During the last few months, many women start feeling heavy and tired, as their baby increasingly takes up more space in their belly. This contributes to many physical signs of late pregnancy, such as heartburn, varicose veins, fluid retention and backache. By the time your baby is due, you may be feeling fed up with being pregnant and just want your baby to arrive!


Other considerations


Remaining pregnancy visits


Your pregnancy visits will now be scheduled a little more frequently. However, the timing of each visit can vary, depending on when your last visit was (26, 27, 28 or 29 weeks), your individual needs and your caregiver's preferences.

Iron supplements


Most women have a blood test around this time to check their haemoglobin for anaemia. If the level is low, your caregiver may suggest taking iron supplements for the remainder of the pregnancy.


Rhesus negative


If your blood group is Rhesus negative (eg. O Neg), you will also need to have a group and antibodies blood test repeated to screen for antibodies.


Kick charts


A kick chart is a graph or grid printed on a piece of paper with spaces to record the daily movements of an unborn baby, usually after about 26 to 28 weeks of pregnancy. Kick charts are not routinely used in Australia, but a few caregivers recommend them for women who have concerns about their baby's movements or women experiencing health complications.


Birth classes


You may start birth classes soon, if choosing to do them. If you haven't booked yet, do this soon so you don't miss out!
