How Many Months Are You Pregnant at Week 3?

At week 3, you are basically in the first month of your pregnancy as well as the first trimester. You still have a long way to go. The journey has just began. The next 8 months are going to be eventful and full of memories you will cherish forever.

Your Baby

Do you know the size of a vanilla bean seed? That’s the exact size of your baby at week 3! Tiny, right? Well, your baby will grow from this tiny size to a full grown baby by the time 9 months elapse. Your baby at this point might be very tiny but you cannot afford to underestimate its potential. During this week, it will make its journey from the fallopian tube to your uterus. In other words, the journey towards a full grown baby has just started! Brace yourself for what promises to be an interesting 8 months ahead!

Pregnancy Week 3: Signs and Symptoms

At 3 weeks pregnant, your pregnancy symptoms are pretty much the same as those of week 1 and week 2. However, you need not to worry. As your pregnancy progresses, the symptoms will also change with time. It is important to note that some women exhibit severe symptoms while for others, the symptoms of pregnancy are mild. What are some of the signs of pregnancy at week 3?

  • Morning sickness: Do you get the urge to puke several times in a day? Well, you are experiencing what is known as morning sickness. Why do they call it morning sickness though? In my opinion, it should be renamed to “all day sickness” owing to the fact that it occurs throughout the day. Time for a petition, perhaps? That aside, in the third week of pregnancy, you will feel the need to vomit several times in a day because of high levels of HCG hormone in your body. It should be noted that not all women experience morning sickness.
  • Spotting: Also known as vaginal bleeding and commonly mistaken for periods, spotting occurs when the fertilized egg implants itself on the uterine wall.
  • Change in your breasts: You might have noticed that your breasts are a little tender, sensitive, sore, and your areola darker. When you experience this, it simply means one thing – you are pregnant!
  • Food cravings and aversions: All of a sudden you are craving foods you didn’t crave before.
  • Mood swings: One minute you are happy and the other minute you feel like crying or annoyed for no particular reason. Pregnancy hormones make you moody.

Is It A Boy Or A Girl?

This question is bound to crop up sometime down the line whether we like it or not. While the sex of the baby is determined at the time of the egg being fertilized, it might be a little too early to determine the sex of your baby in the third week of pregnancy. That said, how is sex determined? Care for a biology crash course?

Of course you do or so I presume. You see, when the egg is fertilized it essentially contains 46 chromosomes. 23 chromosomes come from the dad and the other 23 come from you. You, the mother, provides X chromosomes only. The dad on the other hand provides either X or Y chromosomes. Here is where the sex of your baby is determined during fertilization. If the X chromosome from the dad fertilizes your egg, an XX zygote is formed which basically means that the sex of your baby will be a girl.

Consequently, if the Y chromosome from the dad fertilizes your X chromosome, the XY zygote is formed meaning you will have a baby boy! I bet this should put to rest the debate of who determines the sex of a baby, right?


Of course, you are itching to know for certain whether you are pregnant or not and keen on going for an ultrasound. The bad news is that an ultrasound at 3 weeks pregnant won’t reveal much. The super tiny fertilized egg is on the move from the fallopian tube to implant itself in the uterus.

You may need to wait another week and carry out an ultra sound in the fourth week of pregnancy. Why is that? Well, in the fourth week of pregnancy, the egg will have implanted itself on the uterine wall and the doctor might be able to see a thicker uterine wall indicating that you are pregnant!

Taking Care of Yourself in the Third Week of Pregnancy

You might already have noticed that your body is undergoing drastic changes which is an indication that it’s preparing itself to host a baby. It’s therefore instrumental that you take adequate care of yourself as the safety of your pregnancy is dependent on how well you take care of yourself.

This is the time to adapt a healthy lifestyle. Eat well, avoid smoking and taking alcoholic drinks recklessly, engage in exercises, and get adequate rest. You can also take the opportunity to read pregnancy materials and familiarize yourself with the dos and don’ts during pregnancy. Above all, avoid things that give you stress. Stress is bad for your pregnancy. Endeavor to keep your stress levels low.

Your Partner- A Few Tips

The apple of your eye just conceived.  This is not the time to be insensitive or a prick. This is the time to support the future mother of your baby. I understand that you could have fears or concerns. The best course of action is to sit down with the mother of your kids to be and address any concerns. It doesn’t matter whether the baby was planned or not. This is unchartered waters and you need to provide all the moral support and assure her that all will be well. Share in her joy, help her address any fears she might have and assure her that everything will be alright. This is the time to show her that you are her ride or die kinder partner!

Final Take

Congratulations are in order. You are now 3 weeks pregnant. The journey has just started and the end result is dependent on how well you take care of yourself during this whole period. You may just be 3 weeks pregnant but you have a whole 8 months ahead. Take the necessary supplements, eat the right diet, exercise, sleep in the right position, avoid unhealthy eating habits and above all, consult your doctor if you notice something unusual. You will get through the third week, move on to the fourth week of pregnancy and before you know it, you will be holding the bundle of joy in your hands!
