Can’t breathe!!!

According to my LMP I’m 6 weeks 1day. I don’t go in for my confirmation until March 8th. I’ve had a previous miscarriage so I did get my blood work done and labs looked great. More than doubled. My boobs/nipples hurt ever since I found out. (They were not like this with my last pregnancy) I have come down with a cold. (I got one last pregnancy but it wasn’t this bad.) I’m so congested, can’t breathe and terrified to take anything. Anyone have any natural remedies or advice for this worried momma.
