Could I possibly have a child?

Hey guys! I don't know if this has happened to anyone before, Its quite funny though. Just the other day I was online going through my social media feeds and comments, I came across a post of one of my ex (My first I would say). It was a picture post of a little cute boy with the caption "happy birthday My baby" since we broke up we haven't seen eachother but I remembered a time she mentioned to me that I ones impregnated her and she had to abort it secretly knowing it's going to be too much for me to handle. Immediately I saw the post what came to my mind was oh! Does she have a child now? and the next minute I was thinking oh I never heard she got married. And then, if she actually gave birth back then the child would be around same age this baby is or is it possible that she never aborted the baby? Again I thought to myself this baby is so cute ooo and I think he looks like me. Lol.... funny right? Well as at the time it wasn't funny to me. Although I was not interested in finding out from her though but I kept following the comments on that particular post until she mentioned in her reply to a comment that the boy happens to be her nephew. It was a sigh of relief for me and I couldn't stop laughing at myself for having such thoughts.
