34 weeks marks eight and a half months of pregnancy and is considered preterm birth. A woman's gestational period lasts 280 days, calculated from the first day of her last menstrual period, with seven days constituting one gestational week, totaling 40 weeks. Pregnancy is divided into ten months, each comprising four weeks. By 34 weeks, the fetus has largely developed and fetal movements are relatively stable. Going into labor at 34 weeks indicates preterm delivery. At this stage, the fetus is fully developed and has excellent viability, generally capable of normal survival.
