Hello, Yes it's possible if the condom broke, how many dpo are you or when is af due? I don't see anything on your test to indicate your pregnant yet but it could be that the camera is not picking up a very faint line that you can see in person, I remember trying to photograph my faint positives and it was a nightmare.
The line you saw, was it in the time frame and does it have colour to it?
Hope you get the result you want, good luck
