Hi Zola, welcome to healthcare magic.
I don't see anything wrong with you as a couple to get pregnant.
You already get pregnant without any medications, and the response to clomid
In this cycle you have very good chances of getting pregnant if intercourse occurs in the proper time.
As for the miscarriages there is a big list of investigations to be done, I would suggest screening for diabetes
functions as a start.
Finally for the delay in getting pregnant I suggest that your husband should have a recent analysis.
I hope I have answered your query and wish you get pregnant soon.
Dr. Ahmed Bahaa.
