Dear member, Thanks for writing to healthcare magic. Your concerns at valid. let me assure you your chance of getting a healthy baby is as good as any lady who has never had a miscarriage. Sometimes a baby or embryo if abnormal then it will miscarriage. The chances of it repeating again and again is less than 5%.so the best you can do is do following tests 1complete blood count 2. Thyroid profile and Hba1C 3. Take vaccine for rubella 4. Tab folvite 5mg daily 3 months even before you try for pregnancy . 5. Low dose aspirin 75 mg after pregnancy test positive. your age may not matter much as you are only 30. If above 35 then it s a cause for concern. please get Back with reports. thanks Dr Bhagyashree.
