Condom Hole?

My hubby and I had some fun the other night and we used a condom. Afterward I did the water test (the last one we used broke, so I wanted to be safe). When I filled it with water it seemed fine, then I went to tie it (as a joke I called it a condom water balloon, no throwing was done lol) and as I was doing that I notice a small hole by the tip, some water was coming out, but a very small stream. Is it possible I stretched it too far and caused the hole? Or does it seem like that could've been there during sex? Should I be worried?
