I'm am worried please help

I didn't even know I was pregnant. I thought I was just having period cramps and then I was supposed to start on Friday. I kept having light but annoying pains in my lower right side. I took a test on Saturday and it was positive. This is my first pregnancy, and everything I look up on the internet tells me it could quite possibly be an ectopic pregnancy. This worries me a lot. But I have had no bleeding and have had no issues with periods or my reproductive system through out my life time. I'm a little worried on what to do. I don't want it to be attached in a tube for the next few weeks before I can get to an appointment, and the pains get worse. But I also want to know that everything is going alright. I'm a newbie please help!!
