Low lying placenta at such an early  stage usually resolves when  uterus enlarges in size  .You need not worry about it at present....Most of the miscarriages take place before 12 weeks and u crossed  that...so no increased  risk

Nothing to worry it will move up as pregnancy progresses

Take rest it will move up
