Opinions?

I sent a nude to a random guy on Snapchat the day before I started talking to my now boyfriend. And I feel terrible. But I didn’t know I was going to meet him the very next day. I don’t know what to do I’m also worried it might come up in the future but the guy didn’t screenshot it or anything I don’t think. It was before I met him clearly. I just feel guilty and I know it’s wrong and I regret it so much.
