Crepe myrtle growing sideways

[Bambichik39]

So I found this Muskogee crepe myrtle half off at Lowes for $20. I was super excited because I had been searching for one but didn't have the $150 the nurseries wanted. I figured they are fast growers so I wasn't too worried about small size. After planting and pruning it's still pulling left on the top- I believe from sitting on a pallet and growing towards the sun. Will this fix on its own or so I need to commit crepe murder to get it to straighten up?
