i hope someone else weighs in here but the fetus is pretty small at 5 weeks and 104 degrees is only about as bad as a fever. provided that you don't drink any more during the pregnancy i would think the risk of birth defects would be relatively low. it can depend also on how drunk you got. but a qualified and trusted ob/gyn would be able to give you better numbers about risk.
what is the chance of birth defects from getting drunk in a spa at 104 degrees for about an hr? (at 5 weeks pregnant). my boyfriend and i are unhappily considering terminating our pregnancy because we got drunk in a 104-degree hot tub for about an hour when i was 5 weeks pregnant. (l found out the next week). we've seen what children and parents of children with developmental issues can go through. background: i'm 37 and he's 40. we're both pretty healthy and i'm jewish. i'm thin and always have been and i eat well and work out regularly. i'm now at 7 wks. have we raised our chances of birth defects? by how much?
