I want to know if there's something wrong with my health. I noticed sometimes I discharge a white or a yellow sticky that leaves a bad odor on my pants and makes my panty wet.

If the discharge has a fish like smell, it is likely that you have bacterial vaginosis - characterized by a high pH in the vagina (more than 5). Twenty percent of all women have experienced this.
It is a condition more than an infection - meaning one has to change the environment to get rid of it. Every time you kill the bad bugs with antibiotics or disinfectants, they will soon come back.
The most effective way of changing the environment is by "feeding" the good lactic acid bacteria - then they will grow and produce acid and make the vagina healthy. The best nutrient for these bacteria is lactose. It can be purchased as a vaginal tablet under the name LadyBalance.

I only have smell on the pants when it's dry and it get my panty wet. When I smell the discharge it has no any smell but I see sometimes yellow.
