Help!!!

Tiffanie
I am 4 weeks 2 days pregnant and severely congested.  I have slept about 6 hours in the last two days because I can't breathe.  The doctor told me sudefed was okay to take but it isn't helping.  I've tried Vicks rub, steam, essential oils and nothing is helping.  I can't function.  Any other suggestions.  Thanks yall!
