Hi - it is not reccomended, apart from the possible heat issue, your levels of the chemical that turn you brown are all over the place and you could end up patchy, or end up suffering with what they term 'the mask of pregnancy' which is a brown 'mask' that develops over your face and may not fade completely. There is apparently a risk to the baby as well, according to one of the books I read. Better to get a fake tan if you want to look tanned, and avoid the sunbeds. They are not good for you pregnant or not.
