Am I pregnant?

I know I can find it out with a test but its late at night, pharmacies aren’t open and I’m in the middle of nowhere anyway. I’m really freaking out, so I needed to ask you. I hope some of you are experienced in this.

My last period ended on Sept 3rd. I haven’t got my period yet… I have small itchy bumps all over my body which I researched and couldn’t really find the reason for. Furthermore, I eat a lot… More than usual. Now last time I had sex was on the 9th of September, so I’m not sure whether such symptoms of pregnancy can show NOW.

Any clues? What else should I look out for?
