Help please! emergency!!!

I'm 15 and I'm having trouble breathing!! I woke my mom up and told her and she was like "you're fine" I really can't breathe properly and she just said I was fine... I'm scared I'm gonna die in my sleep.. I feel like Im constantly grasping for air

Anything that can help with this ? ! Since she won't take me to the hospital cause "I'm fine" BTW I had asthma as a baby and almost died twice from asthma attacks. And whenever I get sick I have asthma and can't breathe and I wheez.

I am currently 5 weeks pregnant ... Is this maybe the reason?
