Answer
Hi Crystal,

You can check. You need to pick her up and then place her front half into the tank and then with your dominate hand pinch her body in between you thumb and pointer finger. Squeeze her bond from top to bottom. be careful she might poop on you. If she is gravid you should feel some small lumps.

Look online for a video on palpating a snake.
