Hello
thanks for your query.
There are many causes of bleeding in the first trimester.
It might be the first sign of an impending
miscarriage - that is the main concern.
Sometimes, the developing placenta implants lower down in the uterus, hence bleeding occurs.
Rarely the bleeding is innocuous and does not carry any risk.
However to avert the chances of a miscarriage, it is the common norm to give
Proluton depot ( which is a form of
progesterone ) and HCG - also to support the
pregnancy.
Both these will act to support the growing pregnancy.
Meanwhile, complete
bed rest, avoiding exertion, stress, strain and sexual activity also helps.
At present, there is nothing you can do beyond following the treatment.
You would know the outcome within a week or two.
But do not panic, as with just light bleeding, she may yet continue the pregnancy normally.
Take care.
