Flat Head/Scared momma

Anyone experience flat head with their babies? We have a 6 week old and his head is getting pretty flat but just on the back right side. His head is always turned to the right when he sleeps. I’m really worried as my 20 month old didn’t have this issue. I’ve read to do lots of tummy time, hold him, turn his head, flip him in the bassinet. I’m a SAHM and am afraid we are not doing as much tummy time as we need too. Anyone experience this and had to do a helmet or was able to correct on its own. Our pediatrician’s appt isn’t until the end of this month for his 2 month check up but I’m thinking about taking him in earlier to have it looked at.
