What's happening with mum

As you begin to feel more comfortable and grow into your pregnancy it is time to look at other areas of your health. Oral hygiene is very important during pregnancy as hormones can affect your gums and teeth, making them swell, redden or develop bumps and sores. In some cases you may develop pregnancy gingivitis, a growth of bacteria which can be exasperated by the high levels of progesterone.

In very rare cases gingivitis can progress to peridontitis which research has indicated may be linked to pre-eclampsia and premature labour. If you do have symptoms of gingivitis such as red or swollen gums, bleeding of gums while brushing and persistent bad breath, it is a good idea to arrange a check up with your dentist or oral hygenist who can advise you best on how to alleviate symptoms.


What's happening with baby

Baby is now about the size of an orange and their senses are developing sufficiently that they can now sense light through eyelids which are still closed and as the bones in their ears harden they can hear your voice and your heartbeat.

Baby's hair follicles are now busy growing languno, a fine downy hair which will cover their entire body and helps protect them from disease and infection as well as insulating them to maintain body temperature.

The Practicalities

This is a good time to start thinking about where and how you would like your baby to be born. Try to gather as much information as you can from your midwife with regards to the facilities and options available.


If you are 15 pregnant your due date is from Monday, 18 March 2024 through Sunday, 24 March 2024.
