Accidentally took too much vitamin D

I went to the doctor weeks ago and was told that my vitamin d levels were extremely low. I believe I was at a 9 at the time. Anyways I was prescribed the highest dose and was told to take it twice a week. I missed a couple weeks and started back taking it Wednesday so I took two pills that day. I forgot that I was only supposed to take it twice a week and took it two pills again Thursday, last night, and today. Do I need to call my doctor or just wait and see if I have any problems as a result of this?
