📖 Trimester

In Detail

First trimester: highest miscarriage risk, organ formation, most intense early symptoms. Second trimester: often called the 'honeymoon phase' — reduced nausea, increased energy, baby begins moving. Third trimester: rapid fetal growth, preparation for labor, Braxton Hicks, nesting instinct. Each trimester brings different prenatal tests, milestones, and considerations. The first trimester is most critical for avoiding teratogens (substances that cause birth defects).
