Low lying placenta

I went to my 20 week scan a few days ago and got told my placenta is low and will need to go back at 32weeks. I have also been put under a consultant and have an appointment with them on Monday. When in the scan I wasn’t that worried when they told me as I didn’t know much about it but when I got taken into a room later and got given a handout on what to look out for such as bleeding and the risks it can cause it has made me panic.

Has anyone had this? Or has this also? Should it be something to worry about?
