-Rise in the Production of HCG!
Now that you are 4 weeks pregnant, it is the time you might slightly start to feel the changes occurring inside your body, although the growth of the baby will not be exactly spectacular. Here is what you should be expecting from this pregnancy week.
Debut of pregnancy symptoms
Since this is the time that would normally coincide with your period, the body becomes more and more aware of the changes happening inside it. If so far you did not experience any, or experienced very few pregnancy symptoms, this week they will start to make themselves known.
4th week of pregnancy symptoms and physical changes that occur in your body
During 4 weeks pregnancy, you will feel differently than the previous weeks. There is an increase in your pregnancy symptoms as they start manifesting on a daily basis.
Physically, you may experience the following symptoms:
- Morning sickness
- Frequent urination
- Light cramping
- Feeling full
- Poor appetite
- Breast tenderness
- Getting tired easily
Morning sickness facts
You can suffer from morning sickness at any time of the day. Still, most of the pregnant women will not experience this until their 6th week of pregnancy. This is due to various changes that are taking place inside your body.
The nausea is perfectly normal but in case it becomes more frequent than 3 times/day and ends up disrupting your life, you may experience hyperemesis gravidarum which will need to be reported to your doctor, so he can help you prevent getting dehydrated. The condition is not very frequent but it helps knowing about it.
How to evaluate early pregnancy symptoms?
If you don’t feel any of the above 4 weeks pregnant symptoms, then it is truly wonderful. But don’t worry about it; it is a perfectly normal condition for some women.
If you are experiencing any of the above symptoms, you need to take care of yourself although there is nothing to worry about.
When you are in week 4 pregnancy, you may feel an overall soreness because of the morning sickness and the body changes you are undergoing. It is natural to experience the first pregnancy back pains and afternoon headaches.
Extra care is a must
You should also remember that the first trimester is a very crucial period for you and your baby since there is a high rate of miscarriages happening at this time. Be very careful and protect yourself from any injuries. In case of an injury, please consult your health care provider as soon as possible.
Care to be taken when you are 4 weeks pregnant
- Take plenty of rest
- Wear a good support bra
- Eat smaller meals instead of larger ones
Egg implantation and HCG
By the end of 4th week of pregnancy, the fertilized egg is implanted more deeply into the lining of the uterus and the amniotic cavity is formed. Your amniotic cavity is filled with amniotic fluid. Once implanted, your body starts producing HCG hormone. This hormone helps to maintain the uterus lining. Also, it sends a signal to your ovaries to stop releasing the eggs each month.
When you are in week 4 of pregnancy, some of you may experience blood spotting as a result of further implantation.
Avoiding strenuous effort
You must be very careful not to expose yourself to extreme cold and stay away from lifting heavy weights or do extremely soliciting activities. The sustained physical effort increases the risk of miscarriage during this week.
Changes that occur in the fetus when you are in week 4 pregnancy
You must know that it is too early to have a 4 weeks pregnant ultrasound as one cannot see anything other than an embryo.
At this week, your 4 week fetus is about .014 to .04 inches long. There are two layers of cells connected to your baby, called epiblast and hypoblast. Two other structures will also develop when you are 4 weeks pregnant – amnion and the yolk sac.
The amnion is full of amniotic fluid that surrounds and protects your growing embryo. The yolk sac will produce the blood and help in nourishing the embryo until the placenta takes over that role.
The placenta, which is in the process of forming during this week, is actually made up of blood and vascular networks which protect your baby along with supplying nourishing nutrients and oxygen.
Fast paced development
Basically, in pregnancy 4 weeks, the home for your little baby is under rapid construction. There are several different layers of cells developing in your baby, which will grow into your baby’s organs and the other body parts. The remaining layers form your baby’s nervous system along with the brain.
During this week the baby grows the arms and legs buds which become visible for the first time. The 3rd pregnancy week is the time for the beginning of the rudimentary movement from the baby’s first blood vessels.
Chances of developing twins
You have 80 percent chances of having twins. They can be fraternal or identical. When two eggs are released and each is fertilized with different sperms, it results in fraternal twins. When the single fertilized egg splits into two, it results in identical twins.
Health and safety tips for pregnancy week 4
As this is the most important time of your pregnancy, you must be very careful throughout the 1st trimester of your pregnancy. Exposure to any harmful substances will cause damage or harm to the developing fetus. So, stay away from the toxins or pollutants that are harmful for you and your baby’s development.
The anxiety attacks are normal and so is the sensibility to certain smells. You may find that you like scents you didn’t like before or that your favorite perfume makes you throw up.
Say “no” to stressful environments
If you are working in a stressful environment be aware of the implications of your nervousness on the baby’s development. Let your coworkers know you are 4 weeks pregnant and try and keep a positive attitude regardless of the urgency of any project.
Make time to think about your condition. It will help you to be aware of the changes happening inside you and also help you offer the baby the perfect psychological environment for this fragile period in its life.
