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, or 1 week after getting "weird" period spotting/bleeding.

Please get examined: Please get an exam by a gynecologist. It's not really possible to say exactly what the cause of your discharge is without a proper exam and lab study of your discharge. On your date I would suggest you refrain from intimate sex and explain that you have to be examined by a gynecologist due to an unusual discharge and you will discuss the results with him afterwards.
