Which is worse?!

Barbara • 28 and pregnant with baby #2!
My husband and and I are going on a cruise in September, which would be worse, being pregnant or having AF?! 
Side note, AF for me last month involved a migraine, getting sick, and a week of cramps. 
We really want to be able to enjoy our vacation, but I don't know which of the above scenarios will be better. Based on the calendar it's either one or the other...
