The second trimester is often considered the most stable and comfortable phase of pregnancy. Energy levels improve, nausea usually decreases, and many women begin to feel physically stronger. However, this stage also marks a period of rapid fetal growth — bones harden, muscles develop, organs mature, and blood volume increases significantly.

The first trimester doesn’t always look dramatic from the outside. But internally, your body is working constantly.
You might feel exhausted by late afternoon. You may suddenly dislike foods you once loved. Nausea can appear without warning. Some mornings feel manageable — others don’t.
