Radiation problems/planning problems

My radiation treatments aren’t going well. After having to have an almost bursting bladder they rescanned me to make a plan on an empty bladder.

Then the new plan didn’t work because my gas/bowel didn’t cooperate meaning my uterus was in the wrong place.

Had one successful treatment after a lot of stress then today the same again happened.

Due to the public holidays and now they are re-planning me I will only have had one session this week.

I’m nervous, don’t they have to be consecutive treatments, has anyone else experienced this?
