What's happening with mum 

Most mums to be are around this time starting to think about the big day and if this is your first child you may become stressed about the actual birth. It is important to keep relaxed and talk to your midwife about any worries you have. 

Continue to get plenty of sleep and relax as much as possible. Your tummy will be heavy now and baby presses on all your systems making it more likely you have heartburn, constant need to pee and muscle pains as the weight of baby presses on nerves.

As amniotic fluid is on the decline and  your cervix will begin to dilate and efface and you may find Braxton Hicks contractions are more frequent. This is normal and is just your body preparing for the big day.


What's happening with baby

At around the 6lb mark, boys tending to be heavier than girls at birth, your baby will be plumping up. The head will be around the same cirumference as the chest and it should be in the birthing position by now although some babies like to wait until the last minute. 

It is getting rather crowded now and there will be less space for baby to move around although he will still practice those vital skills required for the outside world like sucking his thumb and breathing.


If you are 37 pregnant your due date is from Wednesday, 8 May 2024 through Tuesday, 14 May 2024.
