It's not a big problem, just a little blood, which means that there are not many toxins entering your body. The liver has detoxification function and can decompose a considerable amount of toxins. Even if there is a small amount of residue, because the blood flowing through the placenta only accounts for a small part of human blood, the fetus is exposed to fewer toxins, so don't worry too much.
