Unable to sleep in one position

Iam 10w3d days now.. from past couple of weeks i cannot sleep at one position. I used to sleep on my tummy (before pregnancy) but now i cannot even think abt it. Once subconsciously slept, and woke up sharp pain. Now i just sleep left side or right side with pillow beside but i have to switch the sides after sometime, breaking my sleep. Anyone else with me?

Am asking this , coz at 10weeks u hardly have prego tummy.. but why this much inconvenience , wanted to understand.
