Is this ER worthy

I’m 35 weeks pregnant and i just got random shortness of breath that is really bad. It does not change when i switch positions. I literally tried everything. I tried to rest for about an hour and it’s still really bad. I feel like i can barely breathe. The baby is slightly kicking. I’m scared, but i don’t want to waste the hospitals resources. But i also want to know if this has happened to anyone and if their little one ended up being okay.
