Stuffy and can't breathe!

Blair • I'm 25 and expecting my first child June 2016♥️
My nose is always stuffed up and I can't breathe out of it, no matter how much I blow it. It's even worse when I'm laying down or trying to sleep. My mother said it happens to some women during pregnancy and lasts the whole time. I'm 21wks and hope this won't last the rest of the time I have!!! Anyone else struggling with this??
