I never took off my wedding ring with my first. But then again my fingers didn't swell up. They are a perfect fit. Now pregnant with baby #2 and im not taking them off as well. My doc said if u feel comfortable leave them on if not take them off. But leave them on wount make ur finger fall off lol exept if your fingers really swell up.
I just bought a new ring in a bigger size, and put the old one in my jewel box. RockRose said she did the same, with the added fun of having bought her pregnancy wedding band at a pawn shop. I love that story.
If you want to wear something, there is a company called saferingz. They are silicone and only cost about $9.
I'm 15 weeks and have to take off my engagement ring many times. My wedding band had always been a size to big though.
