Sow bug
This is probably a sow bug from the family Porcellionidae, a group known as Porcellionids. These are a type of Crustacean called an Isopod (Order Isopoda), and are referred to as woodlice. They have seven pairs of legs. Pill bugs are in the same order, but a different family (Armadillidiidae). Female sow bugs have brood pouches to carry their eggs, as do pill bugs. Your specimen may be in the genus Porcellio.
Also don't confuse these with a Pill Millipede, a type of Myriapod. Pill millipedes are in the Class Diplopoda, Order Glomerida, and Family Glomeridae. They have 15 pairs of legs and roll up into a tight ball, just like pill woodlice.
