I'm very surprised I didn't get found out in the summer as I went to lots of social events that I normally would have been drinking at but wasn't.
Wimbledon - I wasn't even 5 weeks but did a test before I went as I had suspicions and wanted to know if I could have some Pimms or not! The friend I went with noticed I wasn't drinking (we went out for a nice meal in the evening and would normally share a bottle of wine). She said after the weekend she'd noticed I wasn't drinking and had vague suspicions but didn't think any more of it. She commented that I'd had a bottle of cider but then I informed her that it was non-alcoholic (I made sure I ordered it and not her so that she wouldn't notice).
Local beer festival - an annual tradition with my brother. I was 8 weeks at the time and a group from work were also there, who we met up with. I was questioned why I was at a beer festival but not drinking and I got away with it by saying that I couldn't get home so had to drive (partly true as there are no buses back home after 6pm where I live and I live about 8 miles from the beer festival). I also said that as hubby was working early the next morning I didn't want to burden him by coming to pick me up.
Local weekend music festival - I was about 10 weeks and this was more difficult as we were camping there for four nights and camping normally involves a lot of drinking for me. I took some non-alcoholic ciders and just poured them into a glass so nobody would notice. I had a bit of a brown pants moment when somebody else went into the fridge in out camper and I thought they'd spot them, but luckily they didn't. My brother also bought a nice bottle of wine with him that he'd been given for his birthday and poured me a glass. Hubby could obviously see I felt a bit awkward about it so downed most of it and I just had a the small amount that was left. Then when we went into the arena to see some music I was just ordering Coke at the bar (you weren't allowed to take your own drinks in) and my brother kept commenting that I wasn't drinking. It was a very hot weekend and I just said I was really thirsty and wanted a soft drink.
Family wedding - I was 11 weeks and again I drove. But as the wedding was on my side of the family normally it would be me drinking and hubby driving. My brother did question both me and hubby about why I was driving and we just said that hubby doesn't like driving my car as it's too new and expensive (partly true). As my brother got more lubricated he asked hubby (without me being there) that I don't seem to be drinking much recently and hubby just said that I wanted to cut down. I did have a glass of champagne with the toast after the speeches but drank it slowly and it was after food.
We announced the pregnancy after our 12 weeks scan at a family meal and I told my brother that I was very surprised he hadn't twigged due to me not drinking at several social events over the summer. He said he thought it was odd but didn't put two and two together!
So I got away with it somehow. The most difficult episode was the camping trip as it was a four day trip. It's easy to blag as a one off, but when you're with people day in day out it gets more difficult to find excuses.
