Second trimester of pregnancy: what happens in this phase?

The second trimester of pregnancy is usually the most stable stage of pregnancy.. The mother has assimilated her new state and the fetus has already formed all her organs. Therefore, this stage almost always goes smoothly.

One of the most positive aspects of the second trimester of pregnancy is that many of the annoying symptoms that were present in the first three months begin to reduce and even disappear. The most common thing is that the nausea and dizziness are now much milder or gone.

The normal thing is that there is also more energy and less fatigue. The baby will have a noticeable increase in weight and size and the mother will feel that her pregnancy is more “real”. The second trimester of pregnancy runs from week 13 to week 27. Let’s see the details of this fantastic stage.
