I'm 9 weeks pregnant and I asked my OB if it was okay for me to lay in the tanning bed and he said that as long as my body temp stays relatively normal and doesn't get really high or anything that it won't hurt the baby. But a lot of me friends and family (most of which who are pregnant or already have kids) are telling me my OB is nuts. So From a medical stand point, is it safe to lay in the tanning bed (And not daily or anything, just once or twice a week)?
