5+2 and having one sided pain

Kristina • Mama to 2 boys & 3 step kids
I'm 5+2 weeks pregnant. Starting yesterday, I started feeling one sided pain. It's actually not really pain, more of an annoyance on my right side. No bleeding or spotting. Just the smallest of cramps on my right side. I looked it up and one sided pain comes back to ectopic pregnancy but they describe it as heavy pain with bleeding. I don't have that. 
Should I be worried? Should I go to the ER? Or is this normal?
