Ok I have taken pregnancy test before and it gives me a negative, I also have a cyst that could give me a false negative.. and now I have white discharge.. what does this mean?

A cyst won't effect the results because it won't alter the hormone produced in pregnancy that is being detected on pregnancy tests. Have you missed a period? If so, are your periods normally regular?

Where are you in your cycle? White discharge can be normal at different stages of the menstrual cycle so it may just be due to hormone changes related to that. Even if you haven't noticed it before, sometimes there will be increased amounts.

If you have missed a period, try waiting another week and try another pregnancy test. While it usually will show a positive if you are pregnant as soon as you miss a period, some women find it takes longer to show up. If still negative, see what happens when you are due next month and test again at that time if necessary. You may just be skipping a month, which sometimes happen for no obvious reason. Start to feel any possible pregnancy symptoms before the next month, see your doctor for a blood test.
