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

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

Firstly, you should stop worrying. It’s not possible to put the clock back and stress won’t help you or your pregnancy. 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 in a one-off incident.

You should avoid drinking alcohol in the first three months of pregnancy or if you are thinking of becoming pregnant. If you chose to drink alcohol you should not drink more than 1 or 2 units per week. If this is a problem, seek help.
