Histopathological examination reports on the contents from Uterus after an abortion only confirm that you were
pregnant and some pieces of conception were still there in the uterus after you had an abortion.
Any information worthwhile which can help you in next pregnancy will come from genetic studies on the material obtained from Uterus. The facility is not available in most of the places, and even if you can get it done , not many clinicians will be able to give a precise advice.
So it is an exercise in futility.
