Pregnancy is a significant physiological and emotional phase that typically lasts around 40 weeks from the last menstrual period. It involves a series of stages — conception, embryonic development, fetal growth, and childbirth — each with specific health considerations, routine monitoring, and potential interventions. People planning pregnancy or already pregnant benefit from understanding fertility factors, diagnostic and treatment options such as IVF, and how to coordinate care with a doctor, hospital, or clinic to support a healthy outcome.
