Sore shoulders?

Hannah • 💍 married in 2018. 🤰🏼due with our first 11/18! ✝️ loved and blessed by Christ.

So my shoulders and upper arms are feeling really achy. Not severe pain just sore like the flu. I’ve read about ectopic pregnancies and am worried that’s what I’ve got but I’m not having any pain at all in the abdomen (other than very light cramping last night) and no bleeding. Is this normal to have muscle aches in one particular area?? Trying not to freak out.
