Herpes Carrier?

I found out I have oral herpes? Or carry it? Is what my doctor told me she said I carry the virus? I'm so confused what does that mean? I've never had any mouth blisters or whatever so this is a shock to me. I don't have oral sex so she told me I could have gotten it from sharing a drink from someone. I'm so confused and scared. I carry the virus... What. Anyone else have this? I'm so scared because I'm pregnant does this mean I should not kiss my baby? I won't anyway now
