Sharon,

My DF has just done his dive ticket and it said that pregnant women should not dive. It didnt say when when from. If it were me, and I was pg on the trip, I wouldnt go scuba diving, especially not at 6wks when early pregnancy is the most important.

You should know by the time you are on holidays if you are pg. And if you are then you may just need to snorkle!! And if you arent, then enjoy your diving
