Lack of Pregnancy Symptoms... anyone else?!

I will be 8 weeks pregnant on Wednesday. We have already had our first prenatal apt where we did OB interview, blood test & urine test. Dr said everything is looking good & tests were all normal with “strong positive” on pregnancy test. We have our first ultrasound March 14th & I can’t wait because I need some reassurance. I don’t “feel” pregnant most of the time. Other than being super tired. I have had random times of nauseous but not bad enough to throw up. I’ve also had random cramps but dr said that is normal as uterus grows. I feel bloated & back hurts on occasion but overall I feel fine! Is this normal?? All of my pregnancy apps act like I should be slumped over a toilet miserable counting down the days until 2nd trimester. Should I be worried?? Or am I just lucky? Does anyone have any good stories of past pregnancy’s like this? I know I shouldn’t worry but I can’t help it!
