Hi Alisia,
I can't answer about working as well or being suitable replacements - that is up to your doctor, and of course your own body and the lupus, but there are two drugs asside from plaquenil you can safely use in pregnancy.
Azathioprine (imuran), and steroids (prednisolone etc).
Azathioprine might be an option for you, plus pred as needed, but really your doctor is the only one who can decide this with you.
Cellcept is also on the not reccomended list, so even when you are not flaring you'll need a change of drugs if you want to concieve.
All the very best with the appointment.
