8 weeks still no symptoms, when did you get yours? Reason to worry?

So I am 8 weeks and 1 day and I'm not trying to complain nor brag but I literally haven't felt pregnant at all yet, I've probably felt dizzy momentarily like twice but barely even and over the last two days the stretch marks on my stomach have doubled and are different kinds and weirdly painful, other than that, nothing. No morning sickness, no nausea, no food aversions, or cravings, nothing.

Most of me is sane enough to know it's nothing and my little Bub is most likely there and healthy, but I'd like a second opinion? Has anyone ever not had symptoms in the first trimester, did anyone's come much later than 8 weeks? Am I going to get them at all? And is it totally okay and normal and no reason to worry or get checked if I don't get any symptoms at all? I haven't been able to get an ultrasound or anything yet so I'm just curious. Thankyou all in advance.
