<human>: A few weeks ago I hooked up with a friend of a friend after a party.  When I took the condom off I noticed it appeared to be leaking but I didn't say anything to the girl (stupid, I know, but I couldn't tell for sure if it was leaking or just wet from her plus I didn't want her to freak out).  Today she facebooked me and sent me a message saying "I'm pregnant.  I don't expect anything from you; I just thought you should know." I'm freaking out and don't know what to do.  Do I message her back?  I want to do the right thing, especially since I probably could have prevented this by alerting her about the condom and having her take Plan B. I feel so guilty and want to help but I also am afraid of getting into trouble.  I'm not sure if she's keeping it or what.  I know I'm not ready to be a father (financially or emotionally) but I feel obligated to step up.

Could you distill the essence of the text into 1-3 sentences?
<bot>: One-night-stand just facebooked me telling me she's pregnant.  I'm not sure how to respond.
