slight ache on right side

Whitney
It's my first pregnancy so I'm questioning every little thing. I'm 6 weeks and have had slight aches in my pelvic area since I found out I was pregnant. I seem to have more aches on the right side near my hip.  It's never painful but it is definitely noticeable. After scaring myself on google I'm wondering what the real symptoms of an ectopic pregnancy are. I don't have any bleeding but the aches are worse at night but I'm still worried. Thoughts?? At what point should I be calling a doctor?
