Hi Chocolate,
I found out I was about 5/6 weeks pg with my first a few days ago, in fact the day after coming back from a long weekend with my mum, where I drank wine like a fish, smoked like a trooper (I like(d) a cheeky few with wine!) , and ate loads of 'bad' things like brie and a whole trawler-load of shellfish.
Felt horrified, and went to the docs on Thursday to confirm pg, but also told her what I had been up to last weekend. She just nicely rolled her eyes and told me not to worry, and said that if she had a pound for everyone who came in worried about doing 'dodgy' things in the early stages, then she'd be a rich woman!
So, touch wood, you and I, should be fine. Apparently, generally speaking, if something bad does happen early, then it's more likely to be genetically determined, as opposed to anything you've done.
Not that i'm advocating drinking when pg, but if it makes you feel better, my mum says she was mildly pissed when she went into labour with one of my older brothers in the early 70s, as she claims that it wasn't as much of a big deal back then and a few drinks on a weekend wasn't classed as a bad thing!
On second thoughts, maybe that explains my slightly blase approach to boozing!
