i haven't been on the site before and i haven't got enough time before my conf call to download the booklets and read them, but i just wanted to reassure you that i'm sure your couple of glasses of wine will have done NO harm whatsoever. as long as you reduce drastically once you find out you are pregnant, there's no reason to think that 2 glasses of wine in the first few weeks or so is going to have caused any damage. i had half a bottle of wine with a friend at about week 3 (before i tested), and a couple of glasses the day before i tested, and all seems OK so far!
as for ultrasound scans being bad for the baby - no-one will ever say that they are OK in 100% of cases, so even the info you get from the hospital doesn't say it's not going to cause any problems.
but i think you can probably worry yourself too much about everything, and you do have to focus on the fact that there are far greater risks to your and your baby's health than the scans. as for additives in food - well, if you believe the scaremongerers, we are all doomed because our bodies are pickled in preservatives and additives. generally, our livers are fairly good at dealing with the toxins and as long as you don't live on E102 and E110 during your pregnancy, i'm sure the baby will be fine... if you are worried about it, you could try organic food, and avoid fish like swordfish and marlin which have high concentrations of bad stuff. generally, the lower down the food chain you eat, the less concentrated the toxins will be, so eating lots of fresh fruit and veg (organic or otherwise), and good quality meat and fish will be the best you can do. unfortunately, we can't lock ourselves in pure environments for 9 months, so we have to make the best of the world we live in and what we eat, and hope that our bodies manage to build us a healthy baby at the same time.
i'm afraid i can't help on indigestion tips as i don't ever get it (she says... i'm bound to now!)
