Getting Anxious

I was doing well last week. Then on Monday I started to freak out. I was looking up early symptoms of pregnancy, like I don't know what they are. It made me really anxious. Then today I started feeling like I am going to start my period. I am really freaking out now. It is too early for it though but a lot of time I get symptoms a few days before I start. I started thinking "can I go through this again?" At this point I don't think I can for a while. I definitely need another break. I sure hope I am wrong about AF.
