Placenta praevia

So I had my 25wk apt today. Everything was great - even the baby's arrythmia has corrected itself.  I couldnt be happier.  The Dr. However said my placenta is laying a bit low - although I have no bleeding, they wanna keep an eye around 28weeks and further to see if it'll move out the baby's way. Anyone has gone through this before and can share any experience/advice? Thank u ☺️
