Low lying placenta?

Daniele

I went for my 20 week anatomy scan and the doctor said I have a low lying placenta and that it is partially blocking my cervix. She said it should move away on its own and she would have the high risk doctor look at the ultrasound too. My doctor said we will set another scan at 28 weeks to check on it and wait to hear what the high risk doc says. Should I be concerned?
