Week 36 brings an antenatal appointment, and it is the one people are most tempted to skip because getting anywhere is an effort. It is also the week position stops being provisional: if a baby is still head up, turning may now be offered.
Your body this week
The appointment checks blood pressure, urine and the size of the bump. The NHS makes the case for going in one sentence: these appointments pick up changes you would not be aware of, such as very high blood pressure. ACOG says the same thing about pre-eclampsia — it can be silent, and monitoring is how it is found.
Many babies are engaged by now, meaning the head has moved down into the pelvis. That still does not mean labour is close; it can be weeks away.
Leaking a little urine when you laugh or cough is common as the pelvic floor loosens. Pelvic floor exercises help, and maternity pads are worth having in the house anyway.
What you may notice
Braxton Hicks contractions, sleep problems, stretch marks, sore gums, round ligament pains, piles, headaches, backache, indigestion and heartburn, bloating and constipation, leg cramps, feeling hot, dizziness, swelling, urine infections, vaginal infections, and skin and hair changes.
Movements should not be reducing. This is the point in pregnancy where reduced movements are most often dismissed as running out of room, and that reasoning is wrong.
Your baby this week
Around week 36, the figure given is about 47.4cm from head to heel — romaine lettuce, in the NHS's comparison. It is a population average, and not a measurement of your own pregnancy.
Lungs are usually mature enough to breathe without help by now, and sucking and digesting are ready for feeding.
What care usually happens around now
If a baby is not head down, external cephalic version may be offered: a clinician applies gentle pressure to the bump to encourage a turn, and the NHS puts its success at around half the time.
This is also when the ways babies are born become a concrete conversation rather than an abstract one — vaginal birth, caesarean, and assisted birth with ventouse or forceps, each with what it involves and how recovery differs. The proportions vary between countries and so do the pathways. Ask about your own service rather than reading national figures as a forecast.
This week's tip
Go to this appointment even if you feel fine, and especially if getting there is a hassle. Blood pressure and protein in urine are the two things this visit checks that you cannot feel, and they are the two things most likely to change the plan for the last month.
When to see a doctor
Contact your maternity service the same day for any change in movement, leaking fluid, regular or painful tightenings, or bleeding. Pregnancy warning signs has the full list.
Seek care now: Contact your local emergency services or go to your nearest emergency department if you have heavy bleeding, severe or one-sided tummy pain, pain just below the ribs, a severe headache with vision changes, sudden swelling of the face or hands, a fever, fluid leaking from the vagina, chest pain, trouble breathing, fainting, or a seizure. Contact your maternity service the same day for any reduction in your baby's usual pattern of movement. Femio cannot assess a pregnancy.
Frequently asked questions
What is external cephalic version?
Gentle pressure applied to the outside of the bump by a clinician, to encourage a breech baby to turn head down. It is offered around this stage and works roughly half the time.
Does engagement mean labour is starting?
No. It can happen weeks before labour, and some babies do not engage until labour begins. Week 37 is when full term starts, and week 35 covers pain relief.
