3 Weeks Pregnant

You might be experiencing some early signs of pregnancy symptoms, but it is minor as compared to what will be coming when your hormones fluctuate.


With all that ruffling under the sheets, Mr Sperm has finally met Mrs Egg! Good news mum to be! Your baby is on his or her way!

Being 3 weeks pregnant is being way too early in the game and many a time, you might actually have no idea that you’re actually pregnant.

As conception occurred a few days ago, you might have experienced what a typical period would bring and more…



At 3 weeks pregnant, not much of pregnancy symptoms may be showing just as yet. That’s because most early pregnancy symptoms are caused by pregnancy hormones, and being that early in the pregnancy game, these pregnancy hormones are not at their highest in your body, just as yet.

Being 3 weeks pregnant, here are some signs and symptom that your body might be experiencing:

  • Implantation bleeding. If your little soon-to-be-embryo has successfully found its to his or her new home, you may experience some light spotting as the fertilized egg burrows into the wall of your uterus.
  • Missed period. For those of you whose cycle is typically shorter than 28 days, you might suspect yourself being pregnant as your period is nowhere in sight.
  • Breast changes. Like the typical symptom before each period cycle, you will start to notice that your breasts are getting more sore and tender to the touch. However, one thing that stands out from the typical sore breasts is the colour of your nipples. You will notice that your nipple may be darken as your body begins prepping itself to produce milk.
  • Nausea. As the pregnancy hormone hCG is introduced to your body and making its rounds in your newly pregnant body, you may experience bouts of queasiness, commonly known as Morning Sickness. If you’re experiencing this particular  symptom at 3 weeks pregnant, truth might be, you could be further along than you had anticipated.  
  • Positive home pregnancy test. Upon a missed period, do get yourself a home pregnancy test to check if pregnancy is on the table. For most home pregnancy tests, they are over 99% accurate once you’ve missed your period. However, here is something to take note of: The amount of pregnancy hormone hCG in your body at this time of your pregnancy might not be enough for the home pregnancy home test to detect efficiently—however, the hormone level doubles every 48 hours. As such, should you get a negative result on the first try, try it again after a couple of days followed by a week later with another pregnancy test and continue this cycle just to be sure.
  • Positive blood pregnancy test. At 3 weeks pregnant, you may also wish to do a blood test to find out if you are pregnant. You are able to find out if you are pregnant much faster with a blood test than a home pregnancy test.


As your pregnancy progresses, your pregnancy hormones will fluctuate, and this is what will cause the bulk of your pregnancy symptoms.



Although not much has changed on the outside when you are 3 weeks into your pregnancy, you will however, start to feel some changes. At 3 weeks pregnant, your belly isn’t quite as ready to show since it is only around the 12th week that your belly will start announcing its presence to the world. 

However, you would start to feel slightly bloated. With doctors advising on gaining no more than three to five pounds in total in the first trimester, be careful not to start over-indulging and giving yourself a reason to pig out.

In fact, at 3 weeks pregnant, you should try to eat a healthy, well-rounded diet and to take a daily prenatal vitamin with at least 400 micrograms of folic acid in it.



So the awesome news is that, the fertilised egg is making its way through your fallopian tube, dividing and re-dividing into identical cells on its journey to your uterus.

As mentioned, being 3 weeks pregnant is stilly relatively early to detect the little one via the ultrasound. In fact, the little one is smaller than a grain of salt, making detection all the more tricky.  

But as early as 4 weeks into your pregnancy, your doctor may be able to see an obvious thickening of your uterine lining, which is a sign that the little one has reached his or her destination aka your uterus, for the next nine months.



Reminders for the week:

  • Time to calculate your due date
  • Take a pregnancy test regularly to check if you are pregnant
  • Be sure to take a prenatal vitamin with folic acid daily
  • Time to get do some homework and read up on what to expect in the first trimester
