Found out I'm pregnant, I'm happy but now I have to postpone my wedding...

I've been engaged to my fiancé for about 4 years now. We already have a daughter together and are now expecting our 2nd child later this year. I just found out last Tuesday that I'm pregnant which was a complete shock considering I'm on birth control. I'm about 6 weeks now and I was supposed to be having a cruise ship wedding right around the same time I'd be turning 38 weeks. I had to cancel/postpone because I can't cruise past 24 weeks of pregnancy and while I'm happy I'm pregnant, I'm completely frustrated about having to cancel or postpone our weddings  and losing so much money at such a crucial time. We already had 60 people booked our our cruise wedding, since we'd been planning since last year. My vendors have been super cool about switching dates but Carnival?! Not so much. Cruise deposits are non refundable, non transferable. Considering the fact that we haven't told our guests yet, I'm already nervous that they're going to flip out and ask that I pay back their cruise deposits. With an unexpected baby on the way, paying back 60 deposits won't be easy, especially since 2 days after finding out about the pregnancy, I was told by my doctor that he considers this to be a high risk pregnancy. I need help relaxing. I feel so anxious about everything to the point where my excitement about being pregnant is dwindling down. I just don't want the drama from my guests, and I sure as heck don't wanna hear my guests confront me by saying "you couldn't keep your legs closed until August?!" or something to that effect.
