It's nice to see a thread about this! It's hard to know how our uterus is supposed to feel but I think we'd all expect to feel something
During weeks 8 and 9 I got lots of stretching feelings which to me felt like the opposite of cramps, which I suppose is what they are hehe. Through week ten I had the stretching feeling constantly, it was there from going to sleep at night to waking up the next morning and all through the day, it wasn't painful it was just there! I think that was the week that my uterus was still inside my pelvis but it was getting a bit too big for the space there so it was pressing on things a bit, now my uterus has come above my pelvis that feeling has gone.
I went through a stage of wanting to stick out my tummy, it felt like my uterus was 'bulging' and a bit uncomfortable, again during the time when it was below my pelvic bones.
Now it feels more comfortable but I get the odd cramp or stretch or twinge. I have had a few cervical twinges but not regularly myself.
Also ligament pain is obvious, like little stabs around my uterus in various places, I find yoga helps to get rid of those.
All in all, it is all normal as long as it doesn't give you a lot of pain and you don't have bleeding, so I'm just enjoying feeling things growing and changing in there
