Thanks for the query.
Just by symptoms we cannot come to one conclusion regarding pregnancy
And sometimes urine pregnancy test kit may not give accurate result in early pregnancy.
So you wait for 3 to 4 days and repeat the test or go for blood test
for pregnancy now.
If the test comes negative, the possibility of pregnancy is less.
And you can consult gynecologist and go for withdrawal bleeding.
And can take symptomatic treatment.
