I had a cold sore around the time I had to get blood work. ( I’ve probably only had a cold sore about twice in my life ) it came back good but the only problem was it said I had hsv 1.. now I cannot get over the fact that I might’ve tested positive because of the cold sore at the moment. I had a child a year ago and while pregnant all my blood test came out good. I will be returning to the doctor to do blood work again. But I need to know if this happened to any young ladies.. it worries me & because I used to smoke I figured if I seriously do have it the only result I can think of myself getting this would be from smoking with someone who might’ve had it..
