Even though it's still the week of your period, and some time before you ovulate, try to ensure you're in the best possible health to maximize fertility. One way is to cut down your alcohol intake.
Heavy drinking can reduce the chances of conceiving and, if you do get pregnant, it can also harm your unborn baby's development. There is plenty of evidence that drinking beyond the recommended amounts is harmful. What's lacking is evidence of the effects on conception and pregnancy of the occasional alcoholic drink. There is no known safe level of alcohol consumption for pregnant women. However, many women decide to err on the side of caution and stop drinking alcohol entirely while trying to conceive and in early pregnancy. Some find that morning sickness (see You are 5 Weeks and 3 Days) naturally reduces desire for alcohol.
Alcohol also affects male fertility. It has adverse effects on the quantity and quality of sperm produced, and drinking large amounts can cause impotence.
You may find a drink helps you and your partner relax and puts you in the mood for sex, thereby increasing your chances of conception, but you may want to rethink having the occasional glass of your favorite drink. The US Surgeon General recommends that women trying to get pregnant abstain from alcohol to eliminate potential problems.
