Will my kitten be a maine coon if her mom was full blooded maine coon?

The dads breed is unkown but ive been told he had a medium length coat. She has an m between her eyes and the tip of her ears has a bit of hair coming to a point. She does not have long hair yet( she is 6 weeks) but her coat is a little fluffy but still appears short. If i could upload a picture i would.
