Posting on behalf of a gf who is 20 weeks pregnant. She has as she put it "A colony of cold sores" on her lip and wanting to know is this normal when pregnant?

Both have been searching the net for info but most of the info is in relation to genital herpes...I think it is because your immune system is lower so therefore you are more prone to outbreaks- does that sound about right?

Can you use anything?

TIA
