During this time, the major organs and structures are developing, making the fetus especially vulnerable to environmental influences. Exposure to teratogens during this period can lead to congenital anomalies and developmental issues. However, some teratogens can also have effects later in pregnancy, depending on the timing and nature of the exposure.
