Teratogens will have their most negative impact during the embryonic stage, which occurs during the first trimester of pregnancy. This is when the major organs and structures are forming, and exposure to teratogens can cause serious birth defects or miscarriage. The germinal stage is too early for teratogens to have a significant impact, and while exposure in the second or third trimester can still be harmful, the risk is generally lower than in the embryonic stage.
