Hello,
Since you have very clearly stated that you have a domicile certificate of Gujarat also you have completed your education upto class XII from Gujarat, you will have to provide the Scheduled Caste (ST) category certificate made in Gujarat and signed by the competent authority to extract benefit of reservation meant for ST category candidates. You ca n't use the ST category certificate made in Madhya Pradesh for the same. Also you will be appearing for State Quota counseling so it makes it more necessary to have all the documents from that particular state.
Thank you
