Thanks for the query.
After stopping the birth control the pills the time of recurrence of ovulation can differ from person to person.
And some women may ovulate within 2 weeks after stopping the pills.
If you had intercourse around that period then there is possibility of pregnancy
Just by symptoms we cannot confirm or exclude the pregnancy.
So you wait for 2 weeks after ovulation and if you do not get periods by that time, go for pregnancy test once.
