Can’t get my cup in!!!

So I am a first time cup user and I have trouble getting my cup in! I have the Lena small and I tried to squat, put one leg on the toilet, etc. But I can’t seem to get my cup in! I read that lube helps but I can’t get any lube so I was wondering if there are any other ways to help me. Would coconut oil be safe instead of lube? Help please!

Also I can just get one finger in me
