I can’t seem to find a decent answer to this...

Basically I suffer from endometriosis which makes my periods extremely painful. With my pill I start my period on a Monday which means I take time off work cause I’m in agony.

I want to know if I can start my new pill pack 2 days early so that I start my period on the weekend so I can be at home in agony! I don’t have time to call my doctor because the pill needs to be taken tonight :(
