Anyone else?

This is my second horrible cold since I’ve been pregnant and I’m only 8 weeks. I am so afraid me being sick is going to affect the baby. I have taken Tylenol, Sudafed, Claritin, I do a sinus nasal rinse 3X a day right now..anything else I could be doing? Anyone else have not morning sickness but cold/allergy sickness? I know I probably have developed a sinus infection but my dr doesn’t want to give me any antibiotics...so frustrated!!
