Working Full-time and Exhausted

I'm 20 weeks pregnant with twin girls and I'm feeling really guilty about asking to be put on light duty at work. I'm a full time retail manager and my hours and inconsistent. I am so tired all the time and when I work the late shift I'm even more exhausted and being on my feet for 8hrs is really wearing on my back and legs. I feel bad for asking for special treatment but at the same time I only want to do what is best for my babies. Am I being a whimp?
