Why do toxins cause more medical problems during the 1st 8 weeks of a preganacy rather than the later weeks? - medical problems more condition_symptoms

The toxins are a threat in the first two weeks because the embryo is progressing rapidly. Cells divide continuously and developed the nervous system. After a few months the fetus is essentially developed and it is getting bigger and not the development of vital organs. If the poison is introduced into the first few weeks, the developing fetus May not correct, and there's no way to go and repair the damage as if in the last month or so, if something develops minors wrong - it is easier to treat or repair.
