Your Pregnancy by Trimester:

Which Baby Scan?

For peace of mind please ensure your chosen baby scan clinic is HIS registered and fully insured before booking. 4D babyscan packages are very popular during the 3rd trimester although to ensure the best imaging we recommend that you have this done before 32 weeks. We also offer growth & wellbeing scans and fetal presentation scans. These are available at our Ayr, Glasgow, Motherwell, Falkirk, Greenock & Edinburgh clinics. Book here.

3rd Trimester

You're in the home stretch! Some of the same discomforts you had in your second trimester will continue. At ABC4D we offer 4D scans up to 32 weeks after this point the quality of the images deteriorate due to the ever growing baby. From 34 weeks we offer the Fetal Presentation scan which will demonstrate which part of the baby is presenting first to the maternal pelvis. We also offer the Growth & Wellbeing scan up to 40 weeks. This scan examines and assesses the growth of the baby, estimated fetal weight, amount of amniotic fluid and position of the placenta. 

Weeks 28 – 34

YOU: You will notice that you are not as energetic as before and tiredness is common.  It is harder to get a comfortable night’s sleep.  You might find using extra pillows to support your bump and between your knees helpful.  The skin over your bump is becoming stretched and commonly a little itchy.  Lower backache is common and massage can help to soothe the muscles.  Some gentle exercise like swimming or walking is also beneficial. It is common to lose your appetite or feel full very quickly as your growing bump doesn’t leave much room for your stomach! 

YOUR BABY: This is the stage where your baby is putting on most weight and by the 34th week will weigh about 5 pounds.  Your baby should be kicking and poking you but as time goes on the space for big kicks becomes more limited.  You might notice periods of activity followed by times when your baby seems quiet – this is your baby sleeping and dreaming.  Around this time, your baby should settle into the head down position, in preparation for the birth.  On scan, the baby’s position can be checked to determine whether the baby is head first (cephalic presentation), bottom first (breech position) or lying across the way (transverse).  The baby’s weight can be estimated and measurements of the fluid around baby and blood flow in the cord can be made to assess your baby’s wellbeing.  The position of the placenta can be checked to ensure it does not lie too low and interfere with delivery.

Weeks 35 - 42

YOU: The last few weeks of your pregnancy are very exciting as you get ready to meet your new baby.  Braxton-Hicks contractions may become more frequent as your body prepares for the delivery.  It often becomes easier to breathe and eat as your baby’s head descends and engages in your pelvis. This might put a bit more pressure on your bladder though, as you rush off to the toilet more frequently.  Your breasts frequently begin to leak more colostrum.  Normal term delivery can happen any time from 37 weeks.  Signs that your body is ready are a show (sticky blood-stained discharge), ruptured membranes (the bag of waters surrounding baby breaks) and increasing frequency and intensity of contractions.  Good luck - your baby is on the way!

YOUR BABY: The growth of your baby slows down towards the end of your pregnancy.  Your baby should still move at least 10 times per day.  Scans at this stage in your pregnancy can confirm the position of your baby, the position of the placenta, the estimated weight and well-being of your baby.
