placenta previa at 18 weeks

Sarah • Wife. Momma to a 2 year old. Praying for our rainbow baby.
Just had our Anatomy scan this past weekend and was told the placenta was very low and close to the cervix (also known as placenta previa) i had the scan at the hospital and was told that my ob/gyn who I see this Wednesday will decide if I need to be put on pelvic rest and what other actions we need to take. I'm pretty worried, as I wanted a natural birth. I have a follow up in 8 weeks at the hospital to see if the position of the placenta has moved. Has/is anyone else experiencing this?
