Is it a wild sweet pea?

So I was walking around outside today; and I noticed a bushy green plant that had long, very skinny leafs, curly tips, and pink sweet pea flowers. It also had little pea pods growing heavily on it. As I walked along the side of my house I found maybe 5 more plants all twined togoether and filled with the peas. Is this a sweet pea??? It looks like it. Any characteristics I can know about to tell???
