Some questions I need help

This is my first pregnancy. I'm about six weeks along and my doctor told me not to see her until my eighth week. So all I've had done is the positive blood work saying that I am pregnant. I've been having a little bit of morning sickness but that's about it. The past two days I've had a sharp on and off again pain it almost feels like it's inside my vagina, and the left side. Is this something I should be concerned about?
