Thanks for the query.
If you had unprotected intercourse
around the time of ovulation, there is possibility of pregnancy
Just by symptoms we cannot confirm or exclude the pregnancy.
The spotting you are having could be due to hormonal
Change in life style habits also will affect the menstrual flow.
So you once go for pregnancy test to rule out the possibility of pregnancy.
Then you can go for symptomatic treatment.
