hi, i am 6 months pregnant and developed a cold sore on my lip which healed in 2 days after i applied aciklovir. the doctor requests that i take 3 tests - blood, urine, and sample culture from vagina, he says that only if 3 of them are negative i can go for natural labor otherwise i will have to go through ceserian... but i never had genital herpes and dont have it now, cold blisters on my lips are the only thing that i have.. pls advice
