My cycle is 33 days.. its 23rd day of my cycle.. white discharge and nausea.. can i be pregnant ?

Impossible to say.: It is certainly possible you could be pregnant. Given the information you provided, you have not missed a period so it would be impossible to say at this time. The white discharge and nausea can be caused by many things and deserve evaluation if persist.

Too early to say: Symptoms are not reliable this early. You can do a home pregnancy test 11-12 days after ovulation, or 1-2 days before the expected period.

Possible: with a 33 day cycle, you would ovulate on about cycle day 19. By cycle day 23 you could certainly have conceived, however it takes about 10 days for a pregnancy test to show positive after conception - so it would be about another week before the pregnancy test would answer you question. Good luck.

Take a test: If you think you might be pregnant check then check a home pregnancy test. They are cheap, reliable and available at any pharmacy. On a 33 day cycle one would expect ovulation on day 19 so it is a little early in this cycle for pregnancy to be causing symptoms.
