16 weeks and no symptoms ...

I’m 16 weeks and 3 days and I feel like I have no symptoms of being pregnant anymore...I hear that the second trimester is the “easiest”. But it’s so nerve wracking not feeling pregnant...on top of that I don’t feel like my stomach is showing as much as I’d anticipated...I can feel my uterus above my pubic bone but I don’t know how to find if it’s above my belly button yet...(although I’ve been told by my doctors that my uterus is slightly tilted backwards)

Just nervous and trying not to overthink myself..any tips? Or anyone that’s experienced similar?
