I think I got pregnant on a night when I was very drunk. Will this affect the baby?

Getting pregnant on a night out that includes alcohol is not uncommon.

It takes around 6 days for a fertilised egg to implant in your womb, so it is unlikely that the alcohol you drank that night would have done any lasting harm. Therefore, you can probably stop worrying. And anyway, it’s not possible to put the clock back and stress won’t help you or your pregnancy.

You should avoid drinking alcohol when you're pregnant, or if you are trying for a baby. If you chose to drink alcohol you should not drink more than 1 or 2 units per week. If this is a problem, there are plenty of ways to seek help.
