Lack of symptoms

Abby • Expecting my first after a long journey of ttc
Im 5 weeks two days. And for the last two weeks I've had sore breasts Which has been my only symptom really.
Suddenly my boobs feel back to normal and I'm really scared I've had a silent miscarriage or something. 
The doctor won't offer any hcg tests or anything to put my mind at rest.
I'm going crazy! :-(
