Thanks for the query.
If you had unprotected intercourse
around the time of ovulation, then there is possibility of pregnancy
Sometimes urine pregnancy test kits may not detect early pregnancy.
So if you are having suspicion of pregnancy, consult gynecologist and go for blood test
Blood test will give accurate result compared with urine test.
