is his Herpes or no?

I had an encounter about 2 weeks ago, the first time we've had sex and havent had it since then. I developed a kind of blister like looking rash on the lower left side of the groin. Right above where the gentials start, so pubic area where a condom doesn't cover... It is hardly itchy, i have these bump and they look like they are filled with possible clear fluid which makes me think yes it is... but I am not so sure because I do not have any symptoms what so ever. It isn't uncomfortable, just these blister like bumps, and they day after they appeared the started going down and today have gone down alittle more. Kind really scared I have it... should I go to a med express or something and get this looked at or should I not worry? Also, I shave alot down there soI thought (Ingrown Hair?) but I feel like it'd be far more uncomfortable... also I have read that herpes is white not clear? so what the heck is this...?
