Can I feel my uterus in week 10, lika a little bump?

Uterus. Uterus "comes out" of the pelvis at 12 wks. At that point you can feel like a round ball that is hard.
Congratulations. A thin woman may well be able to feel the enlarging uterus through the skin of her abdomen at ten weeks. You will know for sure soon enough! I'm very glad you are such a good observer of your own body -- it will serve you well in the years ahead.
