Do I need to stop the combined pill before surgery?

Hi,

I have my laparoscopy next week and I've been taking the yasmin pill with both breaks for 3 months as advised by my surgeon but he didn't tell me to come off it before surgery. Is that normal?

I'm stopping it today anyway as my body is hell bent on having a period and I just need to get it out but I will only have been off it for 6 days before going in for the op.
