Early Pregnancy Diagnosis
Excerpt
Pregnancy is the state of carrying a developing embryo or fetus. The human gestational period is 39 weeks and is divided into trimesters, the first spanning from week zero to week twelve. Numerous significant developmental milestones occur as the fetus develops during this time frame. Additionally, as the fetus grows, it becomes visible via ultrasonography, and laboratory testing can be performed to track progression.
