As some of you know, I have 2 lymph nodes on my breast and they cause me to have a very low immune system. Since I'm TTC, what would you recommend me taking OTC that is safe during pregnancy but that could boost my immune system?? I'm always sick. I've had 3 colds in 2 weeks and 4 stomach viruses in 2 weeks. I know, that's real bad. What would you recommend?? cuz I know they sell things OTC but I don't know what would be good. TIA!
