Shortness of breath

Dear Mummies, i’m only 8 weeks in pregnancy. But last night, I experienced the worst symptoms which was shortness of breath. I’ve been having trouble breathing a little (knowing it’s one of the symptoms) but last night, I couldn’t sleep & it feels like someone is sitting on my chest. Yes it was that bad. I had to hug myself and forcefully close my eyes to sleep. Please help. Is this normal? 😢
