I'm 7 DPO and i had a cold sore break out start yesterday on my lower lip. I called in for my Rx of valtrex (generic) and i'm going to pick it up. They have me take 2 pills then 12 hours later take the other 2. This happens every 6 months or so due to the immune suppressants i was on. I plan on talking to the Pharmacist when i pick up the meds but since i dont actually "know" if i'm pregnant or not i have a feeling they will just tell me to take it. Any thoughts?
