Welcome to healthcare Magic!
No, it is not normal, it is a complicated pregnancy
and you can see that she is having regular bleeding.
The good part is that it is not much. She must have full rest till delivery, avoid all kind of travel, take good nutritious diet with good iron supplements
, get hemoglobin
levels and gynecologist visits regularly to avoid unforeseen complications.
There is a hope that as pregnancy would advance with the increasing size of uterus
the placenta would move up and bleeding would be less but that should not make you care free.
I hope the advise would be informative and useful for you.
