I can’t sleep 😩

Idk what’s going on! I’m 16W2D & for the past few weeks i get no rest at night! Anytime i move to switch position to get comfortable i find myself awake. The night seems so long since i wake up like 15 times a night! I work everyday 9-5 and it’s taking a toll on me, idk why this is happening or how to fix it! i don’t have a belly yet so it’s it cuz of that! & i don’t want to take sleeping pills because i know it’ll kick my butt throughout the day at work! Anyone have advice 😖
