IT DEPENDS IF YOU ARE FLYING TO THE SHIP?If not then you need to ask the cruise line as some will have their own rules.If you are flying then I think it may well be a no n.
Hey, don't panic should anything happen all crew both onboard the ship and on the aircraft (should you be using one) are fully clued up on pregnancies and (should they need to) delivering your baby. You will also be either sent to or airlifted to the nearsest hospital should anything start to happen. But always get advice from your GP and have anyone who is travelling with you read up on how to help you should they need to (there'd nothing worse than having people flapping about) x hope all goes well .
I think you will find that most cruise lines don't accept passengers as late on, in their pregnancy as this. Some are 20 weeks, some 24 weeks. You may find one that willl allow you to cruise with them. I'd suggest phoning a cruise specialist such as the number on this website to find out if any are available to yo.
As above, it varies on the cruise line and if fligths are involved. As a general rule, you would need to be less than 28 weeks pregnant to travel.
