I think I got Herpes

I had sex with this girl close to 6 months ago who had herpes but I used an condom and she had no break out her vaginal fluid touched the base of my penis but I had no cuts or scrapes and now much later I found a scab hat has a red sore area around it, would this be herpes?

I never noticed a blister or anything just a scab and then I squeezed it and liquid came out 

Hi, are you experiencing any symptoms such as fatigue, swollen lymph nodes, etc?  Was the girl on antiviral meds?
