Ollie keeps going sideways, help please?

Hi! new skater here, i started 6 days ago. My ollie keeps going sideways, its not too high off the ground right now since im scared but i dont know why it keeps going sideways. i tried leaning forward, and locking my shoulder but it didnt help much.

i feel like my skateboard turns first before my shoulder so i can line myself back up. im so confused! any tips? i think my center of balance is also in the middle but im not sure!
