HI,
Recurrent abortions occurring three or more times are due to various factors like fetal abnormality, genetic causes,
Rh blood group
incompatibility and low progesterone hormone, and pelvic factors like infection, endometriosis, fibroids, etc. Hence you will require investigations to find out whether you are fertile or not and also to find the cause of abortions. This will help avert any such mishaps in the future with proper treatment. Consult a gynaecologist.
Hope this helps.
