Pregnancy in weeks: changes in the mother and faetal development

If you're pregnant or planning a pregnancy, you're probably wondering what's going to happen to you and your baby over the next few weeks.

Pregnancy starts counting from the first day of your last period. Even if you haven't actually conceived yet, you're already counting.

Pregnancy starts counting from the first day of your last period. Even if you haven't actually conceived yet, you're already counting.

The union of egg and sperm has created a single cell that begins to divide incredibly quickly. Only now does the real pregnancy begin.

The fertilised egg finishes its journey and joins the uterus this week. It attaches to it, which is called implantation or nesting. Some women only find out they are pregnant now when they miss their periods.

Some women only realise that they have missed their period at this time and start to wonder if they might be pregnant. The best and quickest option is to take a home pregnancy test. A pregnancy test will show you whether the human chorionic gonadotropic hormone hCG, which is only found in the body during pregnancy, is present in your urine.

Your baby is growing at lightning speed, his development is very fast. During this period, body parts and their systems are developing and forming, so he is especially very sensitive to adverse environmental influences.

Your baby is developing and growing in the womb. You are only seven weeks pregnant and nothing is visible on the outside. But your baby is growing at lightning speed.

In the 9th week of pregnancy, the pregnancy hormone HCG is at its peak. This causes the strongest symptoms in the form of morning sickness, mood changes, heartburn and fatigue.

Even if your pregnancy is not yet visible on the outside, big changes are happening in your body. The same is true for your baby, who is in constant rapid development. You can read how your baby is developing this week in our article.

Your baby is still tiny, but it has already formed almost all its organs. From this week on, we no longer look at it as an embryo. But it is already becoming a fetus that will grow and develop until birth.

Your baby already looks like a little person. The embryonic stage is complete and from this week onwards your baby is considered a fetus. All the baby's organs have formed during the embryonic stage. Now they will only grow and mature.

In the last three weeks your baby has doubled in size, growing at a very fast rate. He is already measuring approximately 5-6 cm from the top of his head to his tailbone.

You've only recently found out you're pregnant. You're already 13 weeks pregnant. The fetus is beginning a period of rapid growth. Your belly is starting to protrude and round out.

This period of pregnancy is considered by most expectant mothers to be the most pleasant. Gradually, nausea subsides, energy returns and the tummy takes on the right pregnancy curves.

The second trimester is in full swing. Is it possible to predict the sex with certainty? We will reveal what changes are taking place, but also other interesting facts.
