<s>[INST] Hi My name is sujatha from bangalore, i got married in the year of 2009 and i am planning for a baby. last few months back i was conceived and after third birth got aborted for no reason , and after that i am waiting to get pregnent but its not happening and i dont know whom to consult please help me [/INST] Hello dear, I understand your concern.In my opinion there are different causes for abortion like:-1)Chromosomal anamolies.2)Hormonal abnormalities like thyroid abnormalities,progesterone insufficiency,diabetes etc.3)Infections like TORCH, CMV, malaria, genital tract infections etc.4)Cevical incompetence where in there is short cervix.etc.As the miscarriage occurred after 3 rd trimester the cause might be mostly short cervix.But it is confirmed only after physical examination and necessary investigations.Don't worry once the cause is diagnosed and treated the chances of miscarriage decrease.And all the causes might not get repeated in further pregnancies.Planning the next pregnancy after a gap of 3 months after miscarriage  is a good option so that body gets itself adjusted for further pregnancy and meanwhile the thyroid abnormalities ,genital tract infections, or any should be checked and treated accordingly.Start taking  folic acid supplements one month before planning the pregnancy.So I suggest you to consult gynaecologist and follow the instructions.Nothing to worry.Avoid stress.Hope this helps.Best regards... </s>
