If you don't qualify for an expedite (pregnancy isn't a valid reason - as per the sticky thread), then there's nothing you can do other than wait it out I'm afraid. On the plus side, the NVC side of things is pretty quick at the moment, and I don't think Malaysia has a big backlog, so hopefully once the I-130 is approved the second stage won't take as long.
How pregnant are you? Is travelling to your husband and staying with him in Malaysia an option?
