Worried about boyfriends health...

I’m not sure if this belongs here but lately my boyfriend has been trouble breathing and idk if it’s COVID or what. It could also be because he smokes k kept telling him to call the drs and stuff and he kept putting it off and I hate when he does that we literally are having a baby together and he won’t even change his ways he’s putting himself and me and the kid in danger if he does have COVID and now that he is finally calling them his breathing is so bad he’s been like this for 4 days. He probably won’t even be able to get in until Monday to go to the doctors to see what’s wrong also he always puts away important things because he doesn’t find them important and now this is just more stress on me because I’m worried about his health
