Cold sore

I got a bad cold sore the day I found out I was pregnant. I had not had one before. It finally went away and I feel like another one is forming in the exact same place and I’m feeling so discouraged. I used abreva with my last sore (I don’t feel like it was very effective) and used it again tonight at my first suspicion. I’m really hoping I don’t get another one it’s horrible going to work with this on my face and I’m afraid to go near my sweet son! I also didn’t get any during my first pregnancy.

Anyone else experiencing this issue? Any advice?
