FHA mortgage Loan servicing, payments, escrow account New York

I received a letter in the mail from the bank I chose for my first home loan stating that my monthly mortgage payment would need to be increased because there would n't be a sufficient amount to cover all expenses in the escrow account. It went up almost $200.00 a month. This is after 3 months of payments since we bought the home. Our property tax situation has n't changed so I find it concerning that this happened. Should n't all the calculations have been done by closing to give us a correct monthly figure?
