I am 10 weeks pregnant and it feels like the baby is on my left side what can cause this is it normal?

Normal. The uterus at 10 weeks is the size of a grapefruit and suspended in the pelvis by ligaments. It is very possible that you have the sensation of the uterus on one side or the other depending on your position and surrounding organs. It is too early to feel the baby itself. This usually happens when fetal movement is first felt at 18-20 weeks.
