You should try to follow healthy habits from the time you are trying to get pregnant all the way through your pregnancy. Do not smoke or use illegal drugs, and stop drinking alcohol. Talk to your doctor about any medications you may be taking to see if they can affect your unborn baby. Eat a well-balanced diet .
If you have any chronic medical problems (such as high blood pressure , kidney problems, or diabetes ), talk to your doctor before trying to get pregnant.
Men need to be careful, too. Smoking and alcohol may cause problems with the unborn baby. Smoking and alcohol or marijuana use has also been shown to lower sperm count .
