Hi. I'm Planning In Stopping Taking Micronor Due To Intolerable

Hi. I'm planning in stopping taking Micronor due to intolerable side effects. I had my periods last Sunday, April 3rd and my periods usually lasts 7 days, with intense bleeding and painful cramps. Can I stop taking the pill in the middle of my period or should I finish my pack, which will finish next Saturday April 9th. I know possible side effects from stopping the pill varies from one woman to another but when wiukd it be best to stop taking it, in order to have less side effects?
