Being pregnant makes your skin far more sensitive to the sun that not beign pregnant. There's also the risk of your body temperature getting too high.
Changing hormone levels will also make you more prone to skin pigmentation (colouration). Dark, irregular patches of skin called chloasma sometimes appear on your face. This can be a sign that your skin will react more strongly to UV rays. If you sunbathe or use a sunbed, the dark patches are likely to increase.
Direct and prolonged exposure to UV light also carries the risk of overheating for both you and your unborn baby.
Your unborn baby
There is currently no clear evidence about the effect of UV rays from sunbeds on an unborn baby.
Some studies have suggested that there may be a link between increased UV rays and a folic acid deficiency. This is because UV rays can break down folic acid.
Folic acid is very important in the development of the baby's neural system (brain and spinal cord), which is formed during the first trimester of pregnancy (weeks 1-13).
You should therefore increase your folic acid intake during this period.Here's the links to site re tanning and pregnancy

It's fine to lay out! Just don't let yourself get over heated and you'll be fine :)
U can lay out drink lots of water
Go lay in the sun but don't stay out for too long. And drink lots of water.
Do you mean you want to lie out in the sun but don't think you should, or that you want to go get a spray tan but don't know if it is safe, or what?
