If you smoke or consume alcohol — whether socially or habitually — now's the time to cut it off completely. Since there's no medical consensus on whether or not a safe level of fetal alcohol consumption exists, the Mayo Clinic suggests ditching booze altogether from the time you begin trying to conceive until after your baby is born. Tobacco use has been associated with lowering fertility, as it ages your ovaries and depletes your eggs prematurely, so you shouldn't put off quitting any longer. Quit now, for both your own health and that of your future child.
