Thanks for the query.
As you were in ovulatory period during the time of intercourse and as you didn't use any contraceptive
measure at that time, there is possibility of pregnancy.
But just by symptoms we cannot come to one conclusion regarding the pregnancy.
Your symptoms could also be due to hormonal fluctuation in the premenstrual phase or due to pelvic infection
or part of urinary tract infection
If you are having associated symptoms like vaginal discharge
, burning or pain during micturition etc, better to consult gynecologist once and get examined.
If there are no symptoms other than abdominal pain
, you can take symptomatic treatment with antispasmodics.
And wait till your expected date of periods.
If you miss the periods, go for pregnancy test once.
