Baby Wont Sleep Without Swaddle

Any tips? My baby is 12 weeks and ive been trying to transition her our of her swaddle since she is starting to roll. Ive tried to gradually transition her by doing one arm out for a weel and then doing both arms out before switching to a sack but it's not working. She does okay with one arm out (will sleep from 10:30pm to 6:30am ish) but with both arms out she will only sleep for an hour or so at a time. I just went back to work so I'm exhausted but I'm terrified of her rolling while swaddled. Any advice?
