About 3 years ago in college I had a one night stand with someone from tinder. Lately I’ve been really worried about what ifs. Like that if she got pregnant… I did use a condom however I think I did finish inside. After that day we never talked again and I’m pretty sure we blocked each other and she moved away a month or two after that. I don’t know what to do about the what if’s since I don’t even know her name any more. I just vaguely have the memory. What do I do…
