Welcome! It looks like you have great curl potential. Rather than focusing on curl pattern, work on learning your hair's other properties like texture and porosity because this information will be much more useful in finding the right product. The only thing curl pattern matters for is actual styles and cuts. I wouldn't be able to tell properties from your pictures, but based on you mentioning chronic flat iron use I would guess high porosity. You might want to experiment with protein to help with some of the damage, with the understanding that some damage is not reversible. But if you focus on being gentle with your hair, it will grow in beautifully.
