Why Are Ovashield And Fertisure Medicine Prescribed?

Dr. I am 29 yrs. old. Initially I got pregnant without any medication in the year 2008. But, due to high B.P. the doctor had delivered the baby prematurely and the baby could not be survived due to underweight. Later, I am undergoing treatment without success. Recently, the doctor suggested to take Ovashield, fertisure f for one month. For the second month, he suggested to take pcocare tablets and goodova-100mg from 3rd to 5th day along with fertisure f after the period. Please suggest me whether the treatment is in the right direction or not?
