I understand your apprehension and anxiety, the test itself is not that bad, nor usually that long....maybe bring a favorite magazine or book, heck even your journal if you keep one, you will need to wait after the exam fof initial results and it can take a little while. I found my imagination running wild, so I learned to bring anything that might help distract me.
I have never had a tech who was not pleasant and that is also a help. Ask any questions you may have during the exam, talk to the tech, tell them you have anxiety...all of that can help you get through it just fine. Tell them about your upcoming cruise, or just focus on it yourself...feeling this way right now is pretty normal for MANY women, so do not put any extra pressure on yourself, feelproud that you are being proactivein your health and setting a good example to others!
I hope you have a fab time on your cruise!
