Hello,
There is nothing you can do to prevent a miscarriage at this point. The position where the baby implants is totally random and nothing you have done or could have done would change this. It just happens. The best thing is to just wait and see how it goes. Of course you do not want a miscarriage and I see no reason for an
abortion. If you are unable to keep the pregnancy your body will take care of it naturally. As the uterus grows, a low-lying placenta often moves up and away from the cervix. If it grows completely over the cervix you may have some activity restriction to avoid bleeding. Only time will tell what precautions will be needed. I'm sure your doctor will be monitoring your progress. You can pray for a good outcome and accept what comes to you the best you can.
The emergency contraception should not have an adverse effect if it did not prevent the pregnancy. Though the dosage is higher, the hormones are the same as those your body makes naturally. Ideally you do not get pregnant because of the hormones but if you do, then the effect it might have had did not happen. It has not been associated with increased risk of birth defects.
Best wishes
