Weird feeling where the uterus is

I'm around 11 weeks and I'm a FTM. I was never told about this before or ever discussed it with friends who have been through pregnancy so I don't know if it's normal or not, but my uterus feels so heavy already. I can feel it most of the day. It feels sore and there are certain positions that I find really uncomfortable (sitting with back straight-puts more pressure on the uterus it feels like) like my uterus will pop out of me

Is this normal or should I get it checked out
