Second Time Mama- Minimal Symptoms?

Hey ladies! Second time mom here. Just wondering if anyone else has had very little symptoms? I've been a but more tired than usual and I've had what I think are growing pains in my hips and thighs (I got them very early on with my daughter as well). Other than that, I feel amazing! I'm only 8bweeks but by now I had soooo many symptoms with my daughter. I know every pregnancy is different, but I also had a miscarriage before my daughter so stuff like this makes me paranoid! My first ultrasound is Thursday and I feel so anxious waiting until then. Like, I NEED to hear a heartbeat. Please tell me I'm not crazy 😂
