You will make yourself sick if you continue to stress over this Hun. I can understand, but I have seen a lot of young men and woman in this same situation. I would be more worried if you had actual intercourse than just oral.
It can generally take anywhere from 2-21 days for something to visually appear if you had caught anything. So to answer your question, yes you could have seen something by now. However it is still too early to know 100% sure. You do need around 12 weeks for a blood test at the earliest, unless you visually see something.
Now your doctor can do a swab test, however, the chances are this will come back Neg- and I would still repeat the test, just for your own piece of mind.
So if oral and some licking the only thing that was done, I really wouldn't stress over this, just be more aware in the future.
Although alcohol was involved, I'm sure to some point you were still aware, but just caught up in the moment. So unless she had open sores on her mouth, don't stress.
Keep your appt with your doctor next week, but don't stress Hun. As stated above, be aware, and just keep an eye out for anything.. that way you can bring it to your doctors attention next week.
Hope this helps Hun
