In the third obstetric week, it is necessary to know what is going on in the woman’s body, and it is especially important to understand which influences on it are undesirable now, and which should be avoided without fail. After all, it is now that the direct conception takes place. This time falls in the middle of the menstrual cycle.
We have already learnt that this is the time when fertilisation of the egg takes place. Moving through the fallopian tube, the matured egg moves to the uterus, leaving the ovary. From the uterus, sperm cells enter the fallopian tubes, one of them catching up with the egg. From the moment the sperm and egg fuse, the development of the baby begins.
Its genetic set is the genes of the egg and the sperm. The baby’s sex, skin colour, eye and hair colour, and other innate characteristics have already been determined. In 9 months, a unique person will be born who looks like both dad and mum.
A cell containing a complete double set of chromosomes is called a zygote. Within a day, it begins to divide rapidly. One cell turns into 32 cells in three days, and by the end of the week this number reaches 250 cells. Now your foetus is called a morula and its size is often compared to a grain of sand and its shape to a mulberry.
One of the most important and unique organs, which exists only during pregnancy, begins to form just in the third week. The placenta will bind the mother and the unborn child together, providing it with all the necessary nutrients.
Still characteristic symptoms of pregnancy in the third obstetric week are not noticeable, or even absent. A woman may not notice any specific sensations during this period. Nevertheless, the body of the future mother is ready to accept the fertilised egg, so there is a possibility of the appearance, as well as two weeks earlier, barely perceptible painful sensations in the lower abdomen and lower back, as well as increased libido.
The already known changes in the mammary glands, their engorgement and increased sensitivity may continue.
Change of taste preferences towards salty or sweet is not excluded.
The character of vaginal discharge changes. Mucus helps to protect the ovum from external infections.
If you are worried about severe, sharp abdominal pain, which is accompanied by cramps, see a doctor immediately. This could be a risk of ectopic pregnancy or early termination.
Plan your diet according to all the rules. You do not need to eat for two. Eat full meals, small portions, at least four times a day. Try to steam food.
It is important to realise that fertilisation may not occur in the third week for some reason. It may come later, in the fourth obstetric week. The main thing is not to lose your positive attitude to becoming a mum.
