The 14th week of pregnancy

In the 14th week of pregnancy your baby is the size of a nectarine. During this week of pregnancy, the baby grows rapidly in size and weight. It measures about eight to nine centimetres and has almost doubled in weight compared to the previous week: it now weighs between 45 and 50 grams.

The baby's little heart is beating about 155 times a minute! Their oesophagus, also known as the food pipe, and larynx are now fully formed. Their fingernails continue to grow but the toenails only grow later, around week 18.

Continue to eat a balanced, healthy diet including foods rich in calcium, iron, vitamin C and magnesium. Great sources can be found in things like dark leafy greens, seeds, beans, red meat, oily fish, especially those with bones you can eat like sardines (but be mindful as there are certain fish which should be limited or avoided during pregnancy), red and green peppers, strawberries, whole grains, nuts, dark chocolate, yogurt, avocados and bananas. The list is long, so don’t worry that you will be left with nothing yummy to eat during your pregnancy! You don’t need to eat for two while you’re pregnant, unfortunately that is just a myth, but it is important to eat well, especially now, as for most women the ‘morning’ sickness period has probably (hopefully) subsided. Talk to your midwife or doctor about maintaining a healthy diet throughout the next few months and into postpartum.
