Flying whilst pregnant!

Alison
I am just wondering what people's views are of short haul flights whilst pregnant?
I'm due to fly in August, I will then be 15 weeks pregnant. I feel really apprehensive about doing this, but my other half seems to think it will be fine and the baby will be fine. I will talk to be gp about this, and information on websites says it should be fine, but I'm not so sure?!
