I had 4 missed miscarriages after my marriage. I am 27 years old. All my test reports are normal, root cause is still unknown. I had done Torch test where rubella was positive for which I was give anti rubella vaccination. Rest all test reports are normal like kereotype, sugar, thyroid, ACL etc. I am having no problem in conceiving, everytime in ultrasound, no cardiac activity was present. Also spotting gets start after 1-2 weeks of conceiving. I was taking weekly injections also. Suggest
