Am i pregnant/having pms?it's 2 weeks since sex.i have clear watery discharge(roughly 4 days prior to expected period), my pregnancy test is negative.

Hard to tell...: It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result if done correctly. One can test about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. So, if no normal regular period comes, one can retest in one week.
