Had miscarriage at 7wks then unprotected sex 8-9days later, what's the chance of conception? is it safe this early after miscarriage? i'm 26

Low: The chance that you would ovulate 8 days after completing a miscarriage is not zero, but it is low. If you're concerned you can take a pregnancy test to see if you're pregnant. There are no studies to show that getting pregnant again after a miscarriage has any bad effects on that subsequent pregnancy. Some women, however, like to have at least once cycle before they try again. Best of luck!
