Placenta question??

Arianna • With the love of my life and mother to our handsome little boy ❤️
So I went yesterday to get my anatomy scan. It's a boy!!!!! While the lady was trying to get pictures of him, she noticed that my placenta was placed low, right by my cervix. That kinda worried me. I see my doctor in a week, but to calm myself down, is it normal?? I'm a bit worried.. I just hope it doesn't create any complications.
