I'm sure everything will be fine op.
I think there is a lot of conflicting advice and opinions on alcohol in pregnancy from health professionals in the UK, and it deepens when you look at advice from other countries too.
I think that the majority of pregnancy food and drink related advice in this country is really over cautious and bordering on scaremongering at times.
I have a family member who bizarrely did not know she was pregnant until she went into labour. She had been eating all manner of foods, including those on the 'forbidden list,' and used to frequently drink alcohol, and socialise with people who smoked - including her DH who was a chain smoker. This relative used to drink mainly gin and lager, but also some wine too. She would get merry at the weekend, and have 2 or 3 drinks during the week.
She also didn't take any folic acid or vitamins, nor attend any pregnancy health classes or scans etc, and she gave birth to a very healthy baby who didn't have any development problems.
My Mum and her friends didn't take any vitamins, as they weren't advised to. They followed the food rules as much as they wanted to, but didn't feel pressurised into doing so and would often just eat a food because they fancied it. I think the alcohol advice was a bit more laid back at that time too, and they all drank wine and champagne for celebrations throughout their pregnancies - only ever up to 2 glasses at a time. I didn't have any issue at birth, and neither did my mum's friends children.
