Sudafed generally affects supply only in some women, so if you haven't seen a problem, you may be okay on that front.
Aleve cold and sinus is just a combination of naproxen and pseudophedrine. You're already taking the pseudophedrine, so that wouldn't be a change (and is safe, just may cause a drop in supply.) Naproxen is just a pain reliever, and probably safe (L3)--but unless there's some other reason that it's contraindicated, ibuprofen is probably a better choice.
There's certainly no reason to think that the Aleve Cold and Sinus is less safe than the Sudafed PE that you are already taking, which has both an L3 and an L2 drug. But both are probably fine.
My go-to drug when I'm congested is Afrin nasal spray!
best of luck, and hope you feel better.
