Thanks for the query.
Sometimes urine pregnancy
test kits can give false positive results.
So, if you had unprotected intercourse
around the time of your ovulation better to go for blood test
for pregnancy once.
Which can give more accurate result than urine test.
If the test comes negative, you consult gynecologist go for ultrasound
to find out the possible cause for your problem.
If everything is normal, you may get periods soon or take tablets for withdrawal bleeding.
