Thanks for the query.
Sometimes urine pregnancy
test kit may not detect early pregnancy.
So better to wait for one week and repeat the test.
This can give accurate result or you can go for blood test
for pregnancy now.
If the test comes negative, possibly in one week you will get periods.
If not consult gynecologist once and take tablets to induce withdrawal bleeding.
After getting the bleeding, in the next cycle you can track the ovulation and can plan intercourse around that period. This will increase the possibility of pregnancy .
