If in fact she was a true professional and practiced safe encounters, you really should have nothing to worry about. I do agree with a previous post that neither of you noticed?? Those are two very different sensations and would be difficult to miss. Aside from that, I hate to be the bearer of bad news but get ready for a couple of months of hell! As much as you will try to keep your anxiety and stress levels down, it probably won't happen. You will think about it when you first wake up every day, probably every second waking minute of the day and it will be the last thing on your mind when you go to sleep... Which will be a lot less as well. Now I'm sure every effort has been put forth in researching symptoms of STDs and believe it or not, you may exhibit some of those. That's the stress kicking in, which in turn will compound threefold. How do I know this? Been there. Condom didn't fall off because there wasn't one. Both myself and the SP went through this because of what I sum it up to be a bad judgement call. Not only for my health but hers as well. I mean, what did she know about me? It wasn't until we were both cleared some weeks later that we could both breathe a collective sigh of relief and believe it or not have actually become pretty good friends. Never again will I do something like that! In the meantime, occupy yourself the best you can to avoid the hell. It won't be easy, but after it is all said and done and all is clear, you may actually have a chuckle and say to yourself "why did I worry so much"? Best of luck to you, I'm sure it will be all fine.
