Dear user, welcome to healthcare magic.
The chances of a successful pregnancy after a miscarriage
are very good. Actually what happened to you is just a mishap no more. I see no reason for all these tests and why only these tests? There are many tests to be done like chromosomal studies, screening for diabetes
and anti phospholipid
These tests are only done if you have recurrent abortion (three or more successive miscarriages).
I see that you should have Folic acid
supplementation and go on for the next pregnancy.
I wish you good luck.
