In Traditional Chinese Medicine, the second trimester of pregnancy, spanning roughly weeks 13 through 28, is regarded as a uniquely important and stabilizing phase. It is traditionally called “the period when the fetus becomes secure,” reflecting the belief that the embryo has fully anchored in the womb and that the Chong and Ren channels gradually settle into balance. 

This stage symbolizes a growing harmony between mother and fetus, yet it also marks a time when the mother’s Qi, Blood, and Kidney Essence are increasingly called upon to support ongoing development. From both a cultural and medical perspective, TCM views this trimester as a period for protecting maternal vitality, establishing a strong foundation for fetal growth, and providing gentle, consistent care rather than aggressive tonification. While early pregnancy symptoms such as morning sickness often subside, new and subtler energetic imbalances may begin to appear.
