Pregnancy not only brings unfamiliar changes, but also many questions. Your body reacts more or less strongly to hormonal changes. What you eat during this time is important for your baby. The information on these pages ranges from wanting a child to prepare for childbirth and is intended to be a helpful companion before, during, and after pregnancy.

First Trimester of Pregnancy

The first 12 – 13 weeks are summarized in the 1st trimester. This is the time when every woman keeps her pregnancy to herself as much as possible. In any case, you are mathematically already in the 5th or 6th week before you can even notice anything about your pregnancy. Since problems can sometimes, unfortunately, occur in this early phase, most women do not inform anyone about their pregnancy except their partner. All the greater is the joy than when you can announce at the end of the 1st trimester with little risk of miscarriage: I am pregnant!

Second Trimester of Pregnancy

From the 2nd trimester onwards, experts no longer refer to the fetus as an embryo, but as a fetus. Between gestational weeks 14 and 26, development progresses particularly rapidly. Among other things, this involves the formation of the sex, the skeleton, and the skin layers. Towards the end of the 2nd trimester, the baby’s eyes slowly open. For most women, this is a time to breathe a sigh of relief: initial pregnancy discomforts go bye-bye and the belly is still small enough not to restrict the expectant mom too much.
