Thanks for the query.
If you had unprotected intercourse
around the time of ovulation then there is possibility for pregnancy
Just by symptoms we cannot confirm or rule out the pregnancy. And uterus
cannot be palpated per abdominally till 10 to 12 weeks of pregnancy.
As urine pregnancy test kits sometimes may not detect the early pregnancy, you better go for blood test
for pregnancy which will give accurate result and can rule out the possibility of pregnancy.
