Haven't received a gift from registry....

I have a registry in Amazon and through the thank you notes system I can see who bought things off my registry. My work bought my stroller and car seat back in October, which was super nice of them to do. But I never received it and my baby is due soon and I kinda need to install the car seat in my car. It looks like they mailed it to the office and I'm assuming were planning to give it to me in person. Is it ever ok to ask about it? I have no idea how I would even go about it but I kinda just want to know if I should go ahead and buy one myself or if they are still planning on giving it to me...this is awkward and I don't want to be rude or entitled but I still need the car seat! How would you handle this situation?
