It doesn't sound like Herpes to me, a Herpes lesion would not be blood filled it would present as more of a clusters of fluid filled blisters,and not straight away either,your symptoms are not typical of Herpes at all,it does seem something of a bacterial infection,wait and see if the meds the Doctor gave you help with this,the fact that you felt uncomfortable straight after sex would suggest to me that whatever is going on was already there and the sex irritated it more,I would be surprised if it turned out to be Herpes.
It might be an idea for your husband to be on Suppressive Therapy to reduce the risk of his HSV2 being transmitted to you.

UPDATE I just wanted to say thank you so much for replying to me. At the time I was freakin out and your words were encouraging. It ended up being a cist that had to be drained. My husband has chosen not to take any medication. I will continue to talk to him about it. Thanks sooooooo much for taking your time to volunteer on the forum. It really meant a lot to me.
