Swaddle anxiety

I swaddle my 7 week old son in the halo sleep sac. He had a really bad startle reflux when we brought him home so it’s been a must. He sleeps pretty well in it. The last few nights I’ve noticed he’s been moving in his bassinet more and can now get to one side where he’s sort of turned a bit. Our bassinet is netted luckily and we also have the owlet sock. We do tummy time everyday and he can just barely get his head up (he can hold up his head just fine when being held) and there are no signs of him rolling over but I now have anxiety and fear about him rolling over swaddled in the bassinet. Should I start to unswaddle him now? Am I just psyching myself out for no reason yet since he’s still young?
