symptoms?

i don’t have really any symptoms since i’ve been pregnant other than mildly sore breast, a little bit of fatigue, back pain, and random very short bouts of just feeling nauseous but it passes quickly. i’m 7 week exactly today. this is all i’ve had. is this normal and ok? with my last two pregnancies i was extremely sick and fatigued and had sore breast. i’m not used to feeling so normal and good i guess? that’s what has got me worried. hcg rising properly and progesterone is good. first ultrasound tomorrow.
