Hello welcome to Healthcare magic....
Madam , Repeated abortions after a successful pregancy is usually due to few causes like - Syphilis
, SLE ,Cervical incompetence
...ect these being a major cause . U need to get in touch with an obstretician and get few tests done to rule out these problems. U get a CBC , VDRL
profile , hysterosalphingogram and consult an obstretician with reports..Hope these tests can detect your problem and u can get treated and concieve... Thank you.
