Thanks for the query.
You better repeat the pregnancy
test once again.
If the test comes positive, you consult the gynecologist and get examined to find out the exact gestational age
and if you want you can continue the pregnancy.
If test comes negative, the light bleed you had could be scanty menstrual flow. That can occur due to many causes like hormonal
imbalance, poly cystic ovary disease, anemia
You can consult gynecologist and get investigated to find out the cause for the problem and take treatment accordingly.
