Help!! Maybe hernia maybe not? Idk

Last night I was laying on the couch and felt a little pressure and a tiny bit of pain, so I put my hand down on my lower right abdomen near my pelvic area and felt a small bulge o slowly pushed on it and it went away.. some is telling me this is a hernia and I need to call right away and others that it might have been baby, I’m 23wks along baby is normally super active! After the bulge went away no pain and I’ve been totally fine! I have an appointment next week is this something that could wait? So I need to call today? Should I be concerned? I originally thought it might be baby but now I’m a little more worried. Any thoughts?!
