I am 20 years old. I don't smoke, I don't drink, I don't do drugs. I started my period about two days ago and that's when I started to feel a pressure lower left rib. It's not painful, just annoying and I can only feel it when I'm laying down or sitting. I have anxiety...sometimes severe. It's not tender at the location either. I'm really scared!:-( I've looked up ruptured spleen, lung cancer (crazy, I know) I could go on. I'm terrified it's something serious or it could just be gas.

Does anyone know what I mean?
