Marginal & anterior placentas do occasionally migrate/have clots form. Losses occur with any pregnancy and some increased risk is likely but it is not something they can fix. It does suggest you will eventually deliver by C-section. Follow the recommended diet & precautions. Re-checks will allow them to know when or if other things need to be done.
