Welcome Mrs Vivek Joshi,
Welcome to the forum.
As per your birth details provided above you are born on wednesday under mrigashira constellation Taurus zodiac and Ascendant.
As per your horoscope is concerned you are an negative attitude person and short tempered at the same get tempered more for unjusticefull things which come across your life. At the same time you have religious mindset as well.
I dont know who has prescribed you this blue sapphire i think mainly for progeny or other they would have prescribed you this stone. Frankly speaking instead of helping it will create you bones problem and it will overreact with blood pressure and create some migrain related things and cause huge mental instability after wearing this blue sapphire. So my advice would be to remove this.
