Acceptable weight gain in pregnancy

Hi mommies! Ano lang po ba ang acceptable weight gain during pregnancy? 60kgs ksi ako before mabuntis and Im 30 weeks already pero 8kgs na agad na gain ko. Though normal nmn weight and size n baby as per utz, nagwoworry lng ako ksi feeling ko ang bilis ko lumaki. Normal sugar result last 1st trimester and hnd nmn ako nirequire n OB mag OGTT ulit pero snsbhan niya ako to control diet lng. Ok lng po ba weight ko?
