Almost 8wks no symptoms?

Al

I’ll be 8wks tomorrow and the only thing I feel is sore boobs and peeing more than normal . I’m starting to worry bc I’ve heard this could mean miscarriage. You always hear how horrible pregnancy is with morning symptoms, extreme fatigue, bloating etc...but I’ve yet to experience anything. I feel very normal. I went for an ultrasound sound at 6wks and there was a heartbeat so that made me feel better. But that was 2 weeks ago and I’ve been nervous since then if it’s possible I had a miscarriage since then but I don’t have any spotting or cramping or bleeding. I go to see my doctor on Tuesday and I’m just hoping everything’s ok. Is it normal to not reallt having symptoms at 8wks?
