Is jelly like vaginal discharge a sign of pregnancy?

Hard to tell: It can be hard to tell if a woman is pregnant because some of symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result by 3 weeks after sex (3 weeks after when conception might have been) or 1 week after missing a period. Tests are inexpensive and sold in stores everywhere. We don't look at vaginal discharges to guess about pregnancy.
