welcome to hcm
chances are slightly minimal at this stage..i would advice u to go to the
infertility clinic as early as possible so that u will have plenty of options to have your own baby..first get your egg frozen in the clinic so that u can use it in future as the age alone can get your chances down..
rubella needs to be treated as it is the cause for your mis carriage..u do have treatment..consult a good obg doc and also visit the infertility clinic before its too late..all the best
