Might be pregnant, but addicted to this flavor!

My husband and I think I might be pregnant (will test at my Dr. in a week to know for sure) with our 1st. I don't handle caffeine well, so I've been drinking 6-10 oz. of Pumpkin Spice decaf for the past 2+ years daily. Can you tell me how this is processed and if you have any info about whether it is safe for me to drink while pregnant so that I could run that by my Dr? I've heard that Swiss Water pressed is better. I'm not drinking it now, but would love to resume my routine if it won't cause harm. Thank you!

PS: I also love the German Choco Cake decaf, Creme Brulee decaf, and Cinnamon decaf, so if you have info on those as well, it would be greatly appreciated!
