Shoulder pain in early pregnancy. ..Should I be worried or am I causing myself unnecessary stress! !! 😢

I'm about 5 weeks pregnant and my right shoulder blade started hurting about 4 days ago. Then my left shoulder on yesterday. It's not really pain per say, but more like a mild bothersome knotted feeling or ache. Not sharp or extremely painful. A friend of mine mentioned ectopic pregnancy but I have no severe cramping/pelvic pain and no bleeding. None the less, I have been binge searching the Internet driving myself mad. I don't feel sick at all or have any other inclination that something may be wrong. I have an appointment with my OB on 6/17. Should I worry, should I not? ? 😨😨😨

Has anyone else experience shoulder pains/aches and it was just your body going thru the pregnancy changes?
