Help please

Calli • 18, Due in November, excited & scared mommy to be ❤️
So I'm laying in bed and my chest feels really tight (which isn't uncommon) and my face is tingling. Is this normal in the third trimester or should I be worried? I don't want to wake my fiancé if it's nbd because he has to be up for work in 5 hours.
Yes, I have asthma but I can't find my inhaler anywhere because stuff always gets moved around.
I'm 27 weeks and 1 day.
