I just want to cry. I'm 20 weeks pregnant and this is seriously the 4th time I've been sick. My ear hurts my head hurts my nose burns and I'm stuffy with a runny nose omfg this blows! All I want to do is go to the doctor and get a shot but since I'm pregnant they won't give me one and all the good medicines aren't safe during pregnancy any tips on boosting my immune system?
