The miraculous meeting of an egg and a sperm just happened and a tiny zygote has just formed. Within a few days, the zygote will complete its migration into the uterus and will “nest” there. 3 weeks pregnant, this time you will see the most obvious signs of pregnancy!

The third week of pregnancy marks the time when the strongest sperm meet the egg. At this time, 3 weeks pregnant, the time of conception has begun with a very small cell that is the embryo sac. So what is special about the development of a 3-week-old fetus?

How will a 3-week fetus develop? 3 weeks old fetus has entered the uterus yet?

3 Week Fetal Development: This week is the real start to fetal development. From now until 10 weeks of age, all the organs in your baby’s body begin to develop and some begin to function. Therefore, the baby is vulnerable to any interference in his development during this period.

Right now, your baby is a tiny embryo, consisting of two layers: the dermis and the epidermis, from which all of her organs and body parts will develop.

The primordial placenta also forms two layers. The cells of the placenta create a connection to the lining of the uterus, creating a path for blood to flow so that by the end of this week when the placenta is complete, it will start working and provide nutrients and oxygen to the baby.

Present at the same time is the amniotic sac, the baby’s first home, and the amniotic fluid that will surround the baby until it grows up. The yolk sac appears, which produces red blood cells, which provide nutrients until the placenta is fully developed and ready to take over this task.

So with the question of whether the 3-week-old fetus has entered the uterus, that’s it, mom.

The development of the 3-week-old fetus: How big is the 3-week-old fetus?

If the first 2 weeks, pregnancy is just a very vague visualization through the feeling of small changes in the body, in the 3rd week of pregnancy there has been a clear change. The fetus does exist, even if it is only the very existence of a zygote. The size of the zygote is only 0.35-0.6mm. In general, there is nothing in the image of 3 weeks pregnant, you can only see the tiny zygote.

How has your mother’s life changed?

Will you be able to tell if you are pregnant this week? For the most accurate results, you should wait until the weekend before using the test strip. However, you can still try it now if you want.

If the result is positive, it is advisable to visit the doctor for a more accurate test.

You don’t need to see your doctor regularly until you’re 8 weeks pregnant, unless you have health problems, problems with a previous pregnancy, or are experiencing unusual symptoms. If you are taking any medications, prescription or non-prescription, you need to talk to your doctor right away for advice.

Is it okay to bleed during the 3rd week of pregnancy?

This is one of the earliest signs of pregnancy that is often overlooked by many women. In the first 3 weeks, you may see a few drops of blood like menstrual symptoms for 6-12 days after successful conception because the embryo is attached to the uterus. Usually, the bleeding is very small and lasts from a few hours to a few days.

The development of the 3-week-old fetus and related questions

You are indeed pregnant, joy mixed with anxiety. What to eat, what to abstain from, what to have sex with… Many repeated questions make the mother more worried.

  1. 3 weeks pregnant what should eat and what should not eat?

This is the right time to plan your nutrition for the first trimester. In the first 3 weeks of pregnancy, mothers should supplement with folic acid, iron, and vitamin B1 – three essential nutrients for the body in early pregnancy. Mothers can supplement in pill form or through a daily diet.

  • If you took a folic acid supplement of 400mcg/day before getting pregnant, you will now need a little more, 600mcg/day.
  • During pregnancy, the amount of iron required for the body will double to about 30mg/day. If you do not provide enough, you will develop anemia, affecting the health of the whole fetus.
  • Under the guidance of your doctor, you should take more pills containing vitamin B11, about 0.4mg per day.
  • When they heard the news that they were pregnant, many mothers immediately added a lot of nutrients to their bodies. Too much at this point is unnecessary. According to experts, pregnant women should add about 300 calories to a normal diet.

Some foods to avoid: Foods such as undercooked meat, smoked seafood, or poached eggs … should be avoided because they can pose a risk of coliform infection, toxoplasmosis, and salmonella. These bacteria are not beneficial to the fetus.

  1. Can I have sex 3 weeks pregnant?

For women who are pregnant for the first time, often have anxiety, especially fear that strong sex will affect the fetus, like “the nest of eggs will fall”. However, according to experts, in the early stages of pregnancy, if there are no signs or history of threatened miscarriage, miscarriage, etc., it is still possible to have normal sex.

  1. Can you see the ultrasound at 3 weeks?

In fact, with modern ultrasound technology, you can see the image of a fetus implanting in the uterus from 20 days after conception. So, 3 weeks pregnant, can you see if you have an ultrasound?

  1. Do you still have a normal period in the first month of pregnancy?

The next 6 weeks will be very important for the development of the fetus. The placenta and umbilical cord are already working to provide nutrition and oxygen to the baby. Through the placenta, the baby receives nutrients from the mother’s body, make sure you provide the best for both you and your baby.

If the test is negative, try again the next week if you still haven’t seen your period. Many urinalysis results are not enough to detect pregnancy at 3 weeks.

If you’ve been trying to get pregnant but haven’t been able to get pregnant for a year or more (or 6 months if you’re over 35), see your doctor for a checkup for both you and your partner to find out for fertility problems. It’s a good idea to find out about the problem as soon as possible to help you start treatment and get pregnant soon.

Try the test again: If the test result is negative, do not be disappointed, wait patiently for about a week and try again. Should try early in the morning, right after waking up, the results will be most accurate.

Thus, the mother knows that the 3-week-old fetus has entered the uterus as well as the development of the 3-week-old fetus. Congratulations on your good news!
