Really worried

I noticed a small pimple looking thing on my labia last week and figured it was nothing but this morning I realized I have a bunch of other pimple things on my labia and near my rectum. They seem to have appeared overnight. I also have two raised bumped appear on the back of my hand like last week. I had unprotected sex once weeks ago and I have felt perfectly fine since. I'm seeing a gyno tomorrow but am I driving myself crazy or should I be really worried?
