Thanks for the query.
As you had intercourse around the time of ovulation, there is possibility of pregnancy.
But just by symptoms we cannot come to one conclusion regarding pregnancy.
Minimal spotting can be seen in early pregnancy due to different causes like embedment of gestational sac
, increased blood supply to local genital organs etc.
Some women may get spotting during their expected dates of menstruation
even being pregnant also.
So to come to one conclusion, go for blood test for pregnancy now or wait for 4 to 5 days and repeat urine pregnancy test.
Hope I have answered your query. I will be available to answer followup queries. If you are satisfied with the response, please give your review at the end of the discussion.
