97Ff150 OIL DIPSTICK STUCK

97 f150 HAD IT A COUPLE OF WEEKS,PULLED OUT ORIGINAL OIL DIPSTICK AND THE END WAS SHEARED OFF SOMEHOW. WENT TO WRECKING YARD AND REPLACED THE DIPSTICK YESTERDAY. SINCE THEN I HAVE PUT IT IN 1 TIME, AND CHECKED THE OIL, AND IT WAS OK.
I WENT TO CHECK IT AGAIN AND IT IS CAUGHT ON SOMETHING IN THE TUBE, I GUESS. I THINK I COULD PULL IT OUT BUT IT IS CAUGHT ON SOMETHING. ANY IDEAS ON WHAT TO DO. THANKS, . I THOUGHT I WOULD HAVE TO DROP THE OIL PAN AND GO FROM THERE. THANKS FOR ANY HELP OR SUGGESTIONS
