Your baby's development

Your baby is about 45 cm long and weighs about 2.1 kg. Your baby's digestive system is complete, allowing baby to absorb breast milk after birth. Right now your baby is curled up, legs drawn up to the chest, because the space in your tummy is very cramped. Bless your little darling.

Most of your baby's organs, especially the lungs, are mature at this point. The position with baby's head facing down towards the vagina is called a cephalic (head-down) presentation. The opposite is a breech presentation. However, some babies turn head-down late, so don't worry too much.

Your body

You have reached week 34 of pregnancy. Pregnancy symptoms such as bloating, heartburn and shortness of breath may ease, because most babies have turned head-down towards the vagina, giving your tummy more room.

However, this position also increases pressure on your pelvis and bladder, so you may feel discomfort around your pubic bone, need to wee more often or leak a little urine.

Advice for you

From this week you can consider starting maternity leave if work becomes too hard and tiring. Attend antenatal check-ups regularly so your doctor can check your baby's position as well as the health of both you and your baby.

Kegel exercises help with constipation and reduce haemorrhoids. (In case you don't know yet, Doti would like to share! Kegel exercises are very easy and can be done anywhere without anyone knowing. All you have to do is feel the muscles you usually squeeze when holding in a wee. Squeeze them for 3 seconds, then relax for 3 seconds. Don't tighten your tummy or thighs while doing this).

You should also spend time learning about newborn care. Doti is very happy to share.

And don't forget your deep breathing exercises, or chat with Doti to keep track of your symptoms in a more specific and clear way!
