Lack of symptoms ?

Jamie
Anyone else not really having any symptoms ? I'm between 6-7 weeks and I don't really feel anything ! At night I crash and get really tired and my breasts are sore to the touch but other than that I feel fine all day. Anyone else experiencing this ? I had a transvaginal ultra sound and they could see a slight heart beat on one sac and say another sac which they believe is empty. I am going back in one week! Makes me so nervous how good I feel. Any input will help !
