Honeymoon pregnant

Jill
I'm 12 weeks pregnant. I am excited and not missing alcohol that much but I have my honeymoon in 5 weeks, 20 days in a luxury resort where cocktails will be flowing. I can't help feel sad I can let my hair down and enjoy the luxury with my husband. I feel bad saying it as I am happy to be pregnant. 
When we booked it we had so many talks about partying before trying for a baby but along the way I didn't want to wait. 
I'm just so tired all the time and worried I'll just be bored sitting watching him have fun
