Popping when coming out of Child's Pose

Hi r/yoga, relative newbie to the practice, but was hoping I could get some advice on a simple question.

The start of my practice usually involves coming into Child's Pose, and while I don't have much of a problem getting into the position, when I start to come out into upward facing dog I get a pop in my inside thigh, like where a ligament (adductor?) attaches to the knee. It's been happening each and every time I come out of Child's pose and I'm afraid if I keep forcing that popping it's only going to make things worse. Is there any advice as to what I should do in this situation? BTW I am using a yoga app if it makes any difference.

Thank you to anyone who has anything to say about this
