Should I be worried or grateful?

Hey ladies! I am 23 years old and expecting my first! Of course we are extremely excited! My first and only symptom was incredibly sore and heavy breasts. I have had blood work confirm I am pregnant and my first appointment is Dec. 29th and I should be a little over 8 weeks. In the last 3 or 4 days the soreness in my breasts has went away completely .. I'm terribly worried that something is wrong! I am having NO symptoms! I took a home test this morning and it was positive. Should I be worried at the lack of symptoms or grateful for a easy pregnancy thus far?! Help!
