Having white substance in my underwear and don't know what it is. Had unprotected sex during my ovulation days and been feeling really tired and nauseated and hungry and hurting. Can someone help me.

Have you missed a period? If so, try a pregnancy test. Some women will experience some white discharge in early pregnancy, but it can also be just from where you might be in your cycle.

How late is your period?

White discharge is normal. It happens to every woman. It's when the discharge is colored or foul smelling that there's something to worry about.

If your period is late try a home pregnancy test. Make sure to use first morning urine.

Since you're trying to conceive, tracking your ovulation will help (if you know how to track ovulation). Keep in mind that it can take the average couple 1 - 2 years to conceive. It may not happen this month, but that's no reason to get discouraged. :)
