Fetal Development: Week 13

Select Week Number


Week 13 of your Pregnancy

Your growing baby now measures around 3 inches or 7.6 cm (about the size of a lemon) and weighs about an ounce or 23 grams.

Pregnancy Week 13Baby’s ears and eyes are now in the correct position and his/her body will now start to catch up with his/her head, the nose and chin are well defined and the ribs are developing.

Your baby now has its own unique set of finger prints.

The intestine, which was protruding into the umbilical cord, now fits snugly inside his/her abdomen (tummy).

Tissue that will become bone is also developing around your baby’s head and within his or her arms and legs.

What to Expect

Good news: Most women find the second trimester of pregnancy easier than the first (often called the honeymoon period!).

By now you will probably feel that your breasts are not quite so tender any more, but have noticed that they are increasing in size! Other surprising changes may be that the skin around the nipple and areola may start to darken and your nipples may become more enlarged as well. Some may also notice itching of the skin as your breasts enlarge and veins may become more prominent.

A good fitting comfortable and supportive bra is recommended if you are struggling with your normal bras.

You may also need to wear more loose fitting clothing to adjust for your expanding waistline.

Tips for Week 13

Your uterus has grown in size and is starting to move out of the pelvis – you may just be able to feel the top of your uterus just above the pelvic bone (lying down).

Check that your bra isn’t too tight (which can cause discomfort). It is worth visiting a department store or lingerie shop to be measured and to have your bra size checked.

Childbirth classes are popular and may be booked up, so to get the time slot that suits you best, plan ahead, research and ask for recommendations and sign up for the one you want to attend.
