44wf. had m/c at13weeks.cvs showed perfectly healthy baby girl . what could possibly cause my m/c ? when mydr. tells me it's my age what does he mean by it? i am healthy fit and no genetic abnormalities were found. what other things cause mc at13wks?

Summary: most common cause of miscarriages are genetic trisomies over which you have no control. women over age of 35 have increased risk of chromosomal abnormalities to the fetus. This has nothing to do with your overall health, but more so with how the body changes over time with age. I hope this was helpful. Please reach out for further clarification if needed.
