I found a light blue colored pill in my brothers room, there was a few of them and I'm wondering if anyone can help me identify them. Its almost a diamond shape with soft edges, more like a square but with the top longer then the bottom. The pill has a 37 on one side and three slightly jagged lines on the other, please help I have never seen a pill like this.

Thank you, ps, this is my first post as a new member, hope it goes well
