Thanks for the query.
Your bleeding could be normal menstrual flow which can come one to two days early or late.
It can also be early miscarriage
as sometimes urine pregnancy test kits may not detect very early pregnancy
So as at present you are not having any bleeding nothing need to be done.
If you have any further spotting or pain abdomen etc better to go for blood test
for pregnancy and ultrasound to rule out the possibility of miscarriage and retained products.
