Hi,
No ovarian cyst is unrelated to repititive miscarriages. However there are so many causes behind repitive miscarriages like endometriosis,genetic causes,pelvic inflammatory disease,uterine fibroid,incompetitive cervix,harmonal insufficency etc.You should undergo a complete work up like harmonal check up,one pelvic ultrasound alongwith pelvic examination,vaginal swab if there is any history of discaharge etc.After all these check ups then we can say whats the exact cause behind it.
Thanks,
