Low lying placenta, anyone?

Rowena
Just had a normal anatomy scan today. Glad all is well with my baby girl! I was told by the doctor I have a low lying placenta. I am around 22 weeks along. I was also told that if there is bleeding or abdominal pain I should go to the hospital right away. I have read that the placenta still will go up as baby grows. Anyone had this experience? Appreciate your feedback, many thanks! :)
