Did you get and ultrasound? You can usually see that. But if not, it's pretty unlikely just based on baby kicking in one spot. Much more likely to just be kicking you in an area you can feel more than others. Try not to get to worried about what ifs, they'll drive you crazy! :)
Its possible but not too likely. Most likly the baby is just kicking really hard and stretching out
