Talk to General Physician on Taking High Doses Of Vit D

Plz tag a dietician. I had Vitamin D deficiency. My levels were 21.4 My doctor told me that it should be above 40 at least. He gave me vitamin d supplements and i started taking them. I took sunny D capsules containing 2 lack IU each. I took 3 capsules in one month. So i took 6 lack IU vitamin d3 in 1 month but then i got to know that i had to take one capsule every month and not 3 capsules. After taking last capsule i got tested nd my levels of vit d were 78. But i am afraid of getting vitamin d toxicity because i took such high doses accidently. I stopped taking the capsules after the third capsule. Nd also got my calcium levels tested which were 10.3 first time and 9.7 nd 9.9 after 2 weeks and 4 weeks respectively. I want to know that is taking 2 lack IU capsule after every two weeks normal? Nd am i safe now?
