Physical pregnancy symptoms during week four of pregnancy
It is important to note that every woman’s experience with pregnancy will be unique. In fact, a woman that goes through multiple pregnancies can have a completely different experience every single time.
However, there are some important early pregnancy symptoms you need to note during 4 weeks pregnant because they will help you feel more prepared for the journey. To get informed and prepared, take a look at this list of possible pregnancy symptoms at 4 weeks pregnant.
Light bleeding or spotting
Some women experience implantation bleeding, which is light bleeding or even spotting that happens when implantation happens. Spotting looks like a tiny dot on your underwear, usually light red or pink.
However, if you notice too much blood or if implantation bleeding lasts more than two days, or you have any concerns, make sure to visit your healthcare provider right away, as it could be one of the main early signs of ectopic pregnancy, which needs immediate medical attention.
Feeling bloated and heavy
During 4 weeks pregnant, your body is preparing itself for a baby that it is going to house and grow for the next several months.
During this week, you can expect a bit of bloating. Your uterine lining is getting thicker, making your uterus bigger, which makes you feel more bloated and heavier in the belly area.
Mood changes and overall moodiness
Another main symptom that you (or your partner) might notice at 4 weeks pregnant includes mood swings that seem to come out of nowhere.
These extreme emotions and wild shifts are triggered by increasing pregnancy hormones, and they are the most noticeable in the first and the third trimesters, no matter how many weeks pregnant you are.
Some of the simplest and easiest ways to help yourself feel better during the hormone levels changes and mood swings are relaxation exercises, massages, high-quality sleep, and following a balanced diet.
Tender, painful, and swollen breast
Just like your abdomen, your breasts are starting to prepare for the critical job of nourishing a new arrival at 4 weeks pregnant.
As a result, the number of milk glands increases, and the fat layer also thickens, causing your breasts to enlarge at 4 weeks pregnant. This might also cause breast tenderness and sore breasts.
There is a big chance that you might experience morning sickness and mild cramping at four weeks pregnant.
There is also a big chance that it might not be limited to the early hours of the day; morning sickness can appear at any time of day or night for women in the early stages of pregnancy.
This condition varies from woman to woman, and some feel only mildly nauseated while others do experience vomiting.
Increased vaginal discharge is relatively common and completely normal for women who are in the fourth week of their early pregnancy.
The vaginal discharge should be sticky, clear, or white. If you happen to experience an itchy or vaginal area or if you notice a bad odor, speak to your healthcare provider.
You should not be surprised if you notice that you feel completely exhausted during your fourth week of pregnancy. In fact, you should prepare yourself for being even more exhausted in the upcoming weeks.
Your body is working all day long to create and support the forming baby, and fatigue is a normal part of pregnancy.
What happens to the baby inside during week four of early pregnancy?
Around weeks four and five of pregnancy, the embryo develops and grows within the womb lining. The cells on the outer level, trophoblast cells, reach out to form links with your blood supply, while the cells on the inner level, embryoblast cells, form into tissue layers.
In just a few short weeks, the placenta will be fully formed, and it will start transferring the nutrients to the embryo.
What happens to a woman’s body during week four of pregnancy?
In week four of the pregnancy, the placenta and amniotic sac are starting to form which are necessary for the baby’s development.
The cluster of cells that will soon become your baby will burrow into your uterine lining, where it will remain for the next several months, growing and turning into your baby.
