Should I take another day of bereavement?

Last Sunday my father ped away. I was not super close to him as I didn't see much of him but I am still disturbed and upset about it. I took last Monday (the day after his ping) off from work. I then came back to work for Tuesday and Wednesday. My regular days off are Thursday and Friday. When I came back to work Saturday the weekend lady in charge told me I could have the day off because she thought I was going to be gone anyway. I came back today and she told me that the boss said I would get three days bereavement with pay. We still don't know when a service will be, but it might fall on my days off this week (Thursday and Friday). It's suppose to be an informal service. Anyway, I told the lady that I would kind of like to take tomorrow off, even though I won't be going to any funeral. She said that would be ok and she would tell the boss. But now I am wondering, will that piss them off that I have taken off three days but have not gone to any kind of funeral? What if the service falls on my days off? Is it rude of me to take 3 days off and then the service (if there is one) falls on my days off?
