COULD you get in trouble? Slim maybe. WILL you? Probably not.
If what you wrote was all that happened, and you never solicited for the pic and do not possess or have not downloaded any questionable messages or images of minors, you should have nothing to worry about. Beware, because if they have your email or other contact info from your now-deleted profile, then you may get an extortion attempt message asking for money or they'll go to the police. The messeger could claim to be a parent or authority figure, and it'll be bogus.
Best bet? Stay away from those meat market messaging/social media sites. Meet people the time-honored way - in person.
