6 Weeks Pregnant

Length of baby: 0.64cm (6.4mm)
At week 6, your baby‘s nose, mouth, chin, cheek and ears are already beginning to take shape.


Have you come to terms with the fact that you are going to be a Mother? 

At 6 weeks, you might find yourself more emotional than usual, especially if you are going to be a Mum for the first time.  Some of you may only find out about this piece of good news just this week! If so, congratulations!

Depending on the length of your menstrual cycle, you probably conceived in the 2nd or 3rd week, and are still unaware until you have missed your period.

At this stage you might also be feeling the dreaded pregnancy symptoms, including physical symptoms such as morning sickness and mood swings. And the culprit behind all – pregnancy hormones.



How big is baby at 6 weeks? Your baby is the about the size of a lentil, which is about 0.64cm big.



You are still in your first trimester, so you do not need to gain much weight. By the end of the first trimester (week 12), you should be expected to gain anywhere between 0.5kg to 2kg



It is still early in the pregnancy, or only fourteen percent of the pregnancy to be exact. Some women are experiencing pretty severe pregnancy symptoms at this point, while others are lucky to escape the symptoms. 

Being 6 weeks pregnant, here are some signs and symptom that your body might be experiencing:

  • Spotting. Spots of blood on your underwear or toilet paper is relatively common in early pregnancy, which affects up to twenty five percent of women. These symptoms can however be the first sign of miscarriage or an ectopic pregnancy. If you sense any unusual bleeding, contact your OBGYN doctor.
  • Mood Swing. You might feel a little bipolar in your moods, having elation turn into extreme sadness within seconds. Emotional mood swings are caused by pregnancy hormones, and is totally normal. Your blood sugar level plays a part too, so remember to eat regular healthy meals and snacks to keep your energy up.
  • Frequent Urination. You might find that you are taking frequent trips to the toilet at this point. This is due to the pregnancy hormone hCG directing extra blood flow to the pelvic area. However if you have painful urination or are unable to urinate, you might have contracted urinary track infection, which represents a higher risk starting from week 6 of pregnancy.
  • Sore breasts. The soreness that you experience is your body’s way of preparing the breasts to breast feed the baby. What? This early in the pregnancy? Yep, it’s the body’s way of telling the breast to be ready!
  • Stomach troubles. The pregnancy hormone progesterone can cause trouble in the stomach because it slows down digestion. Do drink more water, eat small meals and eat slowly to counter the bloating issue.


At 6 weeks pregnant, even though your baby is only 0.64cm big, it already has a heart that is beating at 100 to 160 beats per minute.



At 6 weeks, you will look far from pregnant. Though you might feel bloated, you will still not be afforded a seat on the MRT or bus (unfortunately).

At just 0.64cm, your baby is preparing for the growth spurt, but at this stage you can still keep your pregnancy a secret if you’re not ready to share with anyone.



The first prenatal appointment is usually at week 8 unless yours is a high risk pregnancy. So you will have to wait for another two weeks till you get to see your baby via ultrasound.

However if you have done an ultrasound, you might be able to see a fetal heartbeat, depending on how fast your baby is developing.

The baby’s heart will be beating at 100 to 160 beats per minute, almost twice as fast as yours, circulating blood throughout the developing circulatory system.

At week 6, your baby‘s nose, mouth, chin, cheek and ears are beginning to take shape. The intestines, brains, muscles and bones are also rapidly developing, as are the kidneys.

The baby might also be wiggling his or her paddle-like hands and feet, which are now starting to grow.

If you are carrying twins, you will find that out when the doctor performs the ultrasound. If so, you will be able to see two distinct gestational sacs. FYI, the odds are about 1 in 30 births.

If you received fertility treatments, you will have even higher odds of carrying multiple babies.
