Can smoking and drinking affect your pregnancy as early as two weeks?

Your baby develops the fastest during the first trimester - especially the first few weeks. Smoking and drinking during the first few weeks of pregnancy can effect the baby.

Smoking while pregnant increases the mother's risk of having a miscarriage. It also decreases the mother's folic acid which increases the risk for neural tube defects. Smoking during pregnancy can lead to a baby that is small for his gestational age.

Drinking during pregnancy is also linked to an increase risk of having a miscarriage. Additionally, alcohol is associated with fetal alcohol syndrome and the baby could suffer possible fetal abnormalities.

It's safest for the mother and her baby if the mother develops a healthy lifestyle before she becomes pregnant. If you are already pregnant, take the necessary steps to improve your health as soon as possible so your baby doesn't suffer any consequences.
