Sick. Need help.

I am 16 weeks. My husband was sick last week & I guess he passed it on to me.

Congested in face.

Nose is severely stopped up.

Cant sleep.

I have a 2 year old so I have to be functional.

What have you guys taken or remedies that helped you? I am in tears over the lack of breathing.

Will robitussin DM truly help?
