Doctor told me no more calcium??

I forgot to ask his yesterday. My doctor told me to reduce my calcium intake as it could make the baby's bones too strong with in return could make birth very hard. My prenatal comes with a multivitamin, the dha and 600mg calcium. On top of that I only drink milk in the morning which is pored over my cereal. Is this too much calcium? I thought calcium was very good for pregnant women. So now im wondering if I need to stop taking the calcium pill and just eat my cereal with milk in the morning. Anyone else also told to reduce calcium intake ? Seriously confused about this..
