ve never had that happen, usually chafing or some sensitive spots but never a
blister or
blood blister. Should I have any concerns? Or is there anything I may have over looked? I know hsv is usually a cluster, and can sometimes have blood, but is usually filled with the clear liquid and can be accompanied with blood, but never heard of filled with only blood, or looking like a blood blister, so I'm not too worried about that especially being neg at 18 weeks sense possible exposure!
