Could she be lying. Why would she want to lie or get pregnant intentionally by someone she only knew 2 week? I think you are scared, worried, jelous, insecure and threatened of her and the possibility of her being pregnant with what you consider your man.
If he was the love of your life, you both would have never left each other, have unprotected sex with others (at least he did) and now innocent babies having to come to dysfunctional relationships. Only time will tell if she is pregnant and if she is, he has to step up and be financially responsible for this baby. Why don't you just meet with her and discuss your suspision. She will either met with you or blow you off, but it could give you peace of mind and nothing is guaranteed. Only she, her gyne and time will tell. Good luck.
