Antenatal record book - height of fundus, presentation and relation to brim

Height of fundus in pregnancy: By gently pressing on your abdomen, the midwife or doctor can feel your uterus. Early in pregnancy the top of the uterus, or ‘fundus’, can be felt low down, below your navel. Towards the end it is well up above your navel, just under your breasts. The figure should be roughly the same as the figure in the ‘weeks’ column. If there is a big difference (more than two weeks), ask your midwife what action is appropriate.
Fetal Presentation definition
This refers to which way up your baby is. Up to about 30 weeks, your baby moves about a lot. Then they usually settle into a head-downward position, ready to be born head first. This is recorded as ‘Vx’ (vertex) or ‘C’ or ‘ceph’ (cephalic). Both words mean the top of the head.
If your baby stays with its bottom downwards, this is a breech (‘Br’) presentation. ‘PP’ means presenting part, which is the part (head or bottom) of your baby that is coming first. ‘Tr’ (transverse) means your baby is lying across your abdomen.
Relation to brim in pregnancy   
At the end of pregnancy, your baby’s head (or bottom, or feet if they are in the breech position) will start to move into your pelvis. Professionals ‘divide’ the baby’s head into ‘fifths’ and describe how far it has moved down into the pelvis by judging how many ‘fifths’ of the head they can feel above the brim (the bone at the front).
They may say that the head is ‘engaged’ – this is when 2/5 or less of your baby’s head can be felt (‘palpated’) above the brim. This may not happen until you are in labor. If all of your baby’s head can be felt above the brim, this is described as ‘free’ or ‘5/5 palpable’.
Fetal heart sound (FH)   
‘FHH’ or just ‘H’ means ‘fetal heart heard’. ‘FMF’ means ‘fetal movement felt’.
