Will Vitamin D Raise Or Lower Blood Calcium Levels?

I am a 30 year old female who, while having routine blood work was found to have a blood calcium level of 10.4. I went back and had my blood drawn again 3 months later. My blood calcium is down to 10.2 , however my physician ran hormone levels, etc and found everything to be within the normal range except my vitamin d. She has prescribed 50000iu of vitamin d a week. I wasn't sure if this was ok to take, there are so many different articles as to whether this will raise my blood calcium higher or help to lower it. Thank you
