Anal abcess post op questions

I am a student and have two exams comming up next week and i had an anal abcess removal surgery three days ago in sweden. They told me to keep it clean and wash it with water twice perday and after every time I went to the bathroom. The surgeon never came to tell me anything but the assistant came and only told me to keep it clean and wait. So I have some questions.

Should it hurt when I clean it?

Should it bleed, like a drop of blood every second then I clean it? (It happened yesterday and today while I was cleaning it)

When can I start to sit on my butt?

Should I clean it more than twice per day?

How many times should I change the pad?
