EmergenC packets?

Meagan
I've seen some posts about being sick when you're pregnant but I don't feel like hunting those down. Our 8yr old has already come home from school sick and I REALLY don't want to catch it. I'm 13 weeks with a Subchorionic hemorrhage and emotional stress so a cold is the last thing I need right now. Has anyone asked their doctor about EmergenC packets being safe during pregnancy to help your immune system and try to prevent sickness from setting in? The box just says consult your doctor but it takes them forever to return voicemails like that.
