Pregnant wedding ring rash

I've worn my wedding ring for over a year no with no problem. I stared getting a small red itchy spot on my finger while I was on vacation in Mexico (about 2 weeks after my kisses period). I blamed it on the humidity. Came back and cleaned my ring but it would still get itchy. I stopped wearing it for a few days to see if that would make it go away. It did, two days later after I wore my ring again, it came back.

After doing some google research, this is common for pregnant women (I'm only 6-7weeks). Anybody else had it happened?
