Flying and pregnancy.

Ok. I am not pregnant yet, but we have been trying for 9months now.

We are planning a large group vacation in june 2016 in Mauritius. I have heard quite a few poeple saying it is safe to travel when pregnant and then several poeple saying no.

We dont want to spend money on a vacation if there is a possiblity that i might be pregnant and cant fly.

Is there somebody with advice??
