USACA,
I'm not conversant with the US immigration system but I'm assuming that once you know your status will expire after you leave the US, why not apply for extension of your status before leaving? Your husband works in the US so I don't think this should be a problem. You mentioned that your visas had been extended after arriving in the US, does this mean you're limited to extending from within the US only once? I'm not very clear about your predicament, probably if you could explain further, others may be able to help with suggestions.
