Nuvaring won't stay in! HELP!

Jeanny
Please! Somebody help me! I've been using the nuvaring for about 9 months now and this is the first time it just won't stay in! I try to push it in all the way and it just comes back out and stays at the very edges and it bugs the crap outta me! I can't take it anymore, please someone give me advice. Thank you!
