I'd second Jac - if you are pg, the baby hasn't even implanted yet so can't be affected by any alcohol you consume this weekend. In the UK, 1 small drink a day (1 unit of alcohol) is OK, although less is better, so a drink or two now will be OK, just drink slowly or be the driver.
Twinsister, I'm glad I'm not your friend - I'd be on my 3rd or 4th due to lack of drinking and antibiotics, I never want to tell people what I have wrong with me! I mean, my family and friends freak out over pictures of bones or talk of eye operations, so why would they want to know about my internal stuff?
