Baby still breech at 36 weeks

Hannah

My baby has been breech now for about 4 weeks, in the exact same position and doesn't feel like she will move at all. She moves constantly (very active baby) but her position just does not budge. I'm freaking myself out that she is somehow stuck and can't move?? Is that even possible? I was told at 20 week scan she has very long femurs (my husband and I are both tall!) Could this be a reason why? She just doesn't have the room to turn?
