So i woke up this morning feeling perfectly fine. Sat down and skimmed the computer and so forth. Then when i attempted to get up i got terrible cramping. and i went to go to the bathroom and it hurts to bend half way down. I don't know what's going on! 

 

If it doesn't go away within 15 more minutes or so i'm calling my doctor because i'm not sure if this is normal or not

any advice? Have any of you experienced it? This pain is almost unbearable.
