Diaper AND Pump AND laptop Bag?

Alright ladies, I am in the market for the perfect bag. I would love to find one that would hold all of the baby essentials AND a Spectra S1 breast pump + accessories, this will be key for the first 16 weeks, and it would be AMAZING if the same bag could translate to my work bag when I return back to work. In other words still hold the pump and accessories and some baby gear, but ALSO have room for my laptop, notepad, pens etc. taking any and all suggestions :-)
