Thanks for the query.
If you had unprotected intercourse
around the time of ovulation, then there is possibility for pregnancy
. But just by symptoms we cannot confirm or exclude pregnancy.
Urine pregnancy test kits may not give accurate results in early pregnancy sometimes.
So you observe the flow. If the blood flow increase that could be normal menstrual bleed.
If not after 4 to 5 days repeat the urine pregnancy test once. If the test comes positive consult doctor
once and undergo ultrasound
