Wine had alcohol, alcohol can damage the baby this one glass bs I hear is crumb why take a risk
There are risks involved in drinking during pregnancy and it's up to you to decided whether you take those risks or not. Drinking even one unit of alcohol can stop the oxygen to the baby's brain and slow their movement for up to 2 hours, also can lead to fetal alcohol syndrome (Even only occasionally drinking can lead to this). Personally I will not take that risk, but before you decided what to do make sure your aware of what risks are involved.
With my first my midwife told me to save my 1 glass until due date, I did this and she came that day. So u wouldn't if I were u just incase
One glass is okay but not everyday, special occasions etc
