15 Weeks Pregnant

Length of baby: 10cm (100mm)
Weight of baby: 72g (0.072kg)
At week 15, your baby is able to move all it’s limbs and joints.


By now you should be used to the swing of your pregnancy. With the morning sickness slowly ebbing away and you having higher energy levels, you might find yourself having a higher libido aka time to get frisky!

If your partner isn’t too keen on sex with the baby so close by in your belly, remind him that the baby has no idea what mummy and daddy are doing and would not feel anything. More importantly, sex will not hurt or harm your pregnancy.

You might also find what looks like water on the tip of your nipple. This is your milk glands kicking into production. If need be, put breast pads inside your bra.



How big is baby at 15 weeks? Your baby is the size of a pomegranate, which is about 100mm (10cm). The current weight of your baby is about 7.2grams (0.072kg).



This is the weight gain that you must achieve this week.

Underweight(BMI <18.5)  0.44kg to 0.58kg
Normal weight(BMI 18.5 to 24.9)0.39kg to 0.50kg
Overweight(BMI 25 to 29.9) 0.23kg to 0.33kg
Obese(BMI ≥ 30) 0.16kg to 0.25kg

During the second trimester, you will need to eat an extra 340 calories a day.



As you are in the swing of your pregnancy and find yourself in the “honeymoon” period of your pregnancy, you might find your life somewhat being back to normal. However, some symptoms may still creep up from time to time.

Being 15 weeks pregnant, here are some signs and symptom that your body might be experiencing:

  • Stuffed nose. The combined effects of your pregnancy hormones, together with the increased blood flow to the mucous membranes, may cause your nose to be stuffy.
  • Nosebleed. As with the cause of your stuffy nose, the increased blood flow to the nose together with your sensitive nasal passage (increased blood vessel expansion), may also cause you to suffer from nosebleeds.
  • Swollen gums. You might find that your gums are a lot more tender and swollen. In general the gums will be more sensitive during pregnancy, so take extra care of them.
  • Heartburn and indigestion. Because of your pregnancy hormones, you might suffer from heartburn and indigestion. Do take care to avoid foods that might trigger the problem and try to avoid them.
  • Increased sex drive. With your energy up from the past few weeks, you might find yourself wanting to engage in some under the sheet activities.


With milder symptoms and higher energy levels, you might want to have have sex with your partner if you have not been intimate for a while.



At week 15, some mummies might find that they already have an obvious baby bump, while others may not. Regardless, this is not something to worry about since no two pregnancies are the same. Obvious bump or no bump, it’s nothing to worry about at this stage of the pregnancy! 

Furthermore, being a first time mum, your belly could take longer to show. This is as compared to a second pregnancy where the uterus has already been stretched previously and as such, the baby bump might show earlier.

This week, you might choose to undergo the Maternal Serum Screening, which is a voluntary blood test to aid in the risk assessment of Down syndrome. The test measures the amount of AFP (alpha-fetoprotein) and hCG (human chorionic gonadotrophin) which is produced by the foetus and placenta and can be detected in the mother’s blood.

Babies with down syndrome tend to produce less AFP and will usually have a higher level of hCG. This test is usually conducted between week 15 to week 20 of pregnancy.

Another test you might consider between week 15 and week 18 is the Multiple Marker Screening Test (also known as the triple or quadruple screen). This test screens for down syndrome and trisomy 18, which are chromosomal abnormalities, and also neural tube defects such as spina bifida.

If your risk is higher from the tests above, you might want to consider an invasive diagnostic test (which is highly accurate) called amniocentesis to diagnose the condition of your baby.  Amniocentesis is carried out between week 15 and week 18. This test can identify hundreds of genetic and chromosomal disorders, but carries a slight risk of miscarriage.



Your baby is now sensitive to light even though his or her eyelids are fused shut. For example, if you shine a torch light at your belly, you might find your baby moving away from the beam.

Your baby is now also able to move all limbs and joints, and might also start to hiccup inside your belly. Even though there is not much for your baby to taste, he or she is already forming taste buds for life outside the womb.

As soon as next week, you might be able to tell the gender of the baby. This is however dependent on the baby’s position (if the baby is curled up, it will block the image of the sex organ) and the clarity of the ultrasound.



Reminders for the week:

  • Take your screening tests for your baby
  • Treat yourself well
  • Eat healthy and nutritious meals
  • Learn about preeclampsia and amniocentesis
