Just curious, kinda out there! Lol

Well the other day I had bad pains in my ribs and stomach all day!! Never ever has that happened, and then I tried to lay down after work and nap and woke up feeling horrible then before and ended up throwing up a lot! ( sorry tmi ) and just felt bad and then kind of better. Then today my significant other feels bad and threw up. Any relation in that or why? Could it be possible?
