Vitamin D supplement query - too much?

Em

My Obgyn prescribed me a Vit D supplement.

I already take a daily prenatal which is 30mcg (says 200% RDA).

She also prescribed me these daily Calcium tablets which also have Vitamin D in and it says it’s 100% of RDA - 5 and a little symbol I can’t replicate like a u and a g!

Then there is the Vitamin D supplement itself which is one a WEEK, 10,000 IU.

They are all D3... I don’t know it just seems a lot? Does anyone have any info on D3 supplements and can you take too much? I know with some supplements if you take too much the excess just gets flushed out.

Thanks in advance xx
