6 Weeks Pregnant

Emotional highs and lows are especially prevalent at this time. This is due to hormones fluctuating as your baby develops. Hormones aside, your life is about to change dramatically and who wouldn’t feel emotional about that? You will have your first antenatal consultation with your healthcare practitioner. During this visit your first pregnancy ultrasound gives you a glimpse of the developing embryo.

At 6 weeks pregnant, most common pregnant symptoms include:

  1. Fatigue You’re so drained because your body’s still getting used to your changing hormones. Get extra rest if you’re feeling wiped out.
  2. Nausea Hate to break it, but morning sickness doesn’t just happen in the morning. It can be an all-day affair. And moms-to-be who are six weeks pregnant with twins might have even more severe nausea. It’s a good idea to find foods that help settle your stomach and to keep them on hand for regular snacking, since having an empty stomach can trigger bouts of nausea.
  3. Sore breasts Your boobs are likely sore thanks to increased blood flow. Can you believe your body is already starting to prep to breastfeed your baby? Yep, even at just six weeks!
  4. Frequent urination If you find yourself having to pee more than usual, it’s because the pregnancy hormone hCG is directing extra blood flow to the pelvic area. Heading to the bathroom more often is normal, but if you have painful urination or have the urge to go but are unable to, tell your doctor right away. Those are signs of a UTI, which you’re at higher risk for starting at week 6 of pregnancy.
  5. Gas and bloating The pregnancy hormone progesterone can cause these tummy troubles. Drink lots of water and eat fiber-rich foods to avoid constipation (yuck), which contributes to bloating (double yuck).
  6. Mood swings Yup, crankiness and emotional extremes are because of the hormones. Fatigue and fluctuations in blood sugar can contribute too, so get extra rest and regularly eat healthy meals and snacks to keep your mood (at least sort of) in check.
  7. Cramping and spotting At 6 weeks pregnant—and any time in early pregnancy—cramping and spotting are both normal. We know these symptoms can make you worry about problems like ectopic pregnancy at 6 weeks and other types of miscarriage. Know that if any abdominal pain is severe (stronger than period cramps) or if bleeding becomes heavy like a period, then you should call the doctor.

Development of Baby

At 6 weeks pregnant, baby is the size of a sweet pea. The average embryo at week six is about .25 inches and will double in size again next week.

Your baby’s heart is beating about 100 to 160 times a minute, allowing for development of her organs.

External features such as the nose, mouth and ears begin to form.

The baby is starting to move; however, these are too gentle to be felt by you yet.


If you did have a 6-week ultrasound, the Obs might be able to see a fetal pole or fetal heartbeat—a clear sign that you’ve got an embryo developing in there. However, if the doctor doesn’t see a fetal pole or heartbeat, don’t panic—you might not be as far along as you thought. The doctor will probably ask you to come back in a few days or a week for another ultrasound.

And yes, if you are six weeks pregnant with twins, you’ll be able to see two distinct gestational sacs on the ultrasound at this point. In fact, twins develop about 4 to 10 days after conception.

Do not be alarmed by spotting, especially if you’re not simultaneously experiencing pain or cramping. Spotting is light bleeding from your vagina, similar to a menstrual period but much less. The colour of the blood can vary from red to brown.

You should, however, consult your healthcare practitioner, as it could also be a sign of miscarriage or an ectopic pregnancy (when a fertilised egg has implanted outside the uterus, this condition can be dangerous for the mother if a rupture leads to internal bleeding).
