Shoulder aching 6weeks pregnant

I’m 6 weeks 4 days pregnant and I’ve started getting shoulder ache it’s not everyday and it’s not like a pain it’s just a dull like throbbing in my shoulder blade or my collarbone, I haven’t had my first midwife appointment yet but my pregnancy is registered online with my doctors, I have tried calling the midwife but I’ve had no luck, I’m am slightly concerned as I no an Ectopic pregnancy is shoulder pain, abdominal pain and bleeding, I have no pain at all just the shoulder aching, I’ve also seen shoulder aching/pain can be caused by dehydration which I’m hoping that’s what it could be, I just need some reassurance and no what’s going on, I will try calling them again on Monday but has anyone had shoulder ache and it being nothing and the baby being ok 🙏🏼🤞
