I have gotten cold sores since I was a kid. And very frequently. But honestly while I was pregnant I got them less. They are so gross and embarrassing!
Tell ur Dr they can give u valtrex it gets rid of them immediately I know it's for genital herpes but it also wrks for cold sores I was the same as u my Dr said it's just ur hormones so she called that in for me.
I got them my whole pregnancy !
