Hi I Am 26 Weeks Pregnant And Was Diagnosed With

Hi I am 26 weeks pregnant and was diagnosed with placenta previa at 18 weeks after bleeding. I have had four bleeding episodes at 18,21,22 and 24 weeks since then, all major bleeds. Doctor puts me on cyclokapron IV, bed rest and I go home. I am on bedrest and utrogestan twice daily now until I give birth. Is there anything more I can do to prevent bleeding almost every week?
