Fertility help?

Hello! I have been practicing for a few years now. I posted this same question on another "witchcraft" page and it was deleted which made no sense to me as they allow people to ask questions about how to hex others, cast nonconsensual love spells etc. Anyway, I won't go too deeply in detail about my situation. But I had miscarried with my first baby this time last year. Since then, we have tried and tried with no luck. Does anyone know of any spells or have any suggestions for fertility using candle magick, or anything? I am desperate.

I know medical intervention is the first thing people usually mention, but I have a bit of a complicated situation. My miscarriage was caused by my OBGYN at the time due to medical negligence.(this was confirmed by other doctors/OBGYN s)

I am just asking for anything to better my chances. We've tried so hard and the longing gets worse with time. I feel as if a black cloud has been placed over me with no sun in sight.
