Colds and early pregnancy

6 weeks and 5 days pregnant and came down with a bad cold. My throat is killing me, stuffy nose, very winded and nauseous. Went to urgent care today and they tested me for strep and flu. Came back negative. But other than that they didn’t really do anything. Said it was viral and to take Tylenol and drink fluids. Should I be worried about my baby? I haven’t been to OB yet as they can’t see me till Jan 5. This is my first pregnant so I’m new to this.
